Overview and background

The Archaeology Data Service (ADS) is a digital archive that supports research, learning and teaching with freely available, high quality and dependable digital resources. It does this by preserving digital data in the long term, and by promoting and disseminating a broad range of data in archaeology.

Since 1996 the ADS has provided long-term archiving for multiple forms of data currently comprising around a million individual items generated from archaeological research around the world. ADS holdings include archive and dissemination versions of a number of archaeological journals and the e-Journal Internet Archaeology. Following internationally recognised best practice in the field of digital archiving, the ADS has developed robust, scalable and reliable internal systems and external partnerships that ensure deposited data is both safe in the long run and permanently available to interested users both within academia and beyond. The ADS was awarded the Data Seal of Approval in 2010 and in 2012 won the DPC’s Decennial award for the most outstanding contribution to digital preservation of the last decade.

Ingest and preservation workflow

The ADS follow the Open Archival Information System (OAIS) reference model for digital preservation, ISO (14721:2003), and operate a mix of manual and automated ingest procedures. Long term preservation and access is ensured by rigorous internal procedures and close collaboration with partners in the UK Data Archive. Full details of ADS preservation policy and practice are available here: http://archaeologydataservice.ac.uk/advice/preservation.

Library access to content

Access to all ADS holdings is unrestricted and without charge for all users subject to ADS’s Terms of Use and Access http://archaeologydataservice.ac.uk/advice/termsOfUseAndAccess.

This prohibits commercial reuse of material and requires non-commercial reuse to apply appropriate attribution both to the original depositor and to the ADS.

Auditing of content, policies and procedures (both internal and external activities)

ADS preservation policy is under constant review as part of our commitment to long-term access. Content is managed within the ADS via a bespoke Content Management System designed specifically for ADS holdings and the OAIS reference model. The ADS was awarded the Data Seal of Approval (DSA) in March 2011 (http://assessment.datasealofapproval.org/seals/). This demonstrates the robustness and sustainability of our archival processes. The ADS is an associate member of the Digital Preservation Coalition (DPC) (http://www.dpconline.org/)

Overview and background

The National Library of Spain (BNE) is the institution responsible for receiving the legal deposit of the bibliographic and documentary heritage of Spain on any type of support: books, magazines, maps, engravings, drawings, scores, etc

The Library’s mission is to collect, catalogue, preserve and disseminate this heritage, guaranteeing its integrity and facilitating access for all citizens and future generations.

The digitization of the BNE collections since 2008 and the integration of born digital collections since 2015 generates a new manifestation of its documentary and bibliographic heritage. This allows infinite possibilities of access, dissemination, use and reuse, but also new obligations for the institution: to ensure the long-term preservation of this material, in order to ensure its accessibility and reuse in the future.

Ingest and preservation workflow

Since 2012, the BNE has established a specialized digital preservation software solution compliant with OAIS ISO 14721:2023

The BNE maintains preservation plans for all media-based collections, in order to be able to apply reliable preservation actions based on each media and their context.

The BNE develops and implements comprehensive workflows in order to manage and preserve digital collections throughout their life cycle. Checking the integrity of data in digital collections is carried out in several parts of the workflow. The first check occurs when the preservation metadata file is generated. The second occurs at the time the object is ingested into the preservation system. File validation is also done at this point. Finally, other checks are performed in the audit process over time to ensure that the object has not suffered any conflicts and that the data is the same as when it was initially received. Any discrepancy between the checksums calculated in the audits and those already stored in the database generates an alert that bit decay or data corruption has occurred.

Library access to content

The National Library of Spain must guarantee access and dissemination of its collections in order to promote their use, as a means of cultural, social and economic enrichment.

Thus, copyright free documents can be consulted in the different online repositories.

On the other hand, digital documents under copyright are only accessible in the premises of the National Library of Spain and in regional libraries.

Auditing of content, policies and procedures (both internal and external activities)

The digital preservation system allows check the integrity and authenticity of the different digital collections, auditing them and protecting them from accidental loss and managing the migration of file formats in case they become obsolete. They also allow the migration of a second controlled copy to a backup center in a geographical location other than the Library headquarters.

The Library has established periodic audits of the preserved content.

Overview and background

The British Library has developed a fully scalable, fault tolerant, highly reliable, highly resilient storage system which guarantees the integrity and authenticity of the digital material that is deposited in it. This solution enables us to preserve digital content that we collect but also material that we create, such as digitised collections. The store is an important component of our e-Legal Deposit infrastructure. Under long-standing Legal Deposit legislation, the British Library receives a copy of every printed publication produced in the UK and Ireland. The Legal Deposit Libraries Act 2003 extended this legislation to non-print materials and the Legal Deposit Libraries (Non-Print Publications) Regulations 2013 enshrined the principle that electronic or e-publications and other non-print materials will be deposited in the Library

These publications are saved as part of the published archive, to become an important resource for future generations of researchers and scholars.

Following the Legal Deposit Libraries (Non-Print Publications) Regulations 2013 coming into effect, we continue to work closely with the UK publishing community to collect their electronic content for preservation.

The technical architecture of the digital library system has been developed to enable the British Library to collect and ingest electronic content and for this content to be shared, where permitted, between the Legal Deposit Libraries. All content is replicated to a minimum of two sites.

Overview and background

The Cariniana Network is a distributed preservation network, funded by the Brazilian government, which provides long term preservation and access for Brazil’s scientific publications.

The Cariniana Network's parent organisation is the Brazilian Institute of Information in Science and Technology (IBICT), which was originally established by the Brazilian government in the 1950s, and plays a key role in promoting effective production, management and dissemination of information.

Ingest and preservation workflow

The Cariniana Network uses a Private LOCKSS Network, and subscribes to the LOCKSS Alliance. All the journals that have been preserved in the Network have been registered voluntarily at IBICT's open access services. IBICT has had an agreement with the Public Knowledge Project to collaborate with the dissemination of the OJS platform nationwide since 2008. More than a thousand Brazilian journals have signed the manifest page for the preservation of their volumes in our Network. Guidelines instructing publishers on the rights and obligations of being part of the Network are published on the Cariniana Network Portal: http://cariniana.ibict.br/index.php/publicacoes/item/72-guia-de-preserva....

Library access to content

The Cariniana Network is a dark archive. All the material at the Cariniana Network is open access and once triggered, content will be made accessible under the same terms as originally published.

Auditing of content, policies and procedures (both internal and external activities)

The Cariniana Network follows the model of the LOCKSS Alliance and it has established guidelines and periodical updating of its recommendations for all its institutional partners. The Internal Management Committee is responsible for periodically reviewing the network policies, including recommendations of specific accepted and recommended technologies, as well as the necessary procedures.

The Network services and products are designed to ensure that the Network partners responsibly safeguard copies of the content in independently administered LOCKSS boxes. A small number of representatives of those institutions have controlled access and they participate in independent verification of the integrity of the Cariniana archives, enabling the Internal Management Committee to validate the technical decisions that have been taken over time.

Overview and background

The CLOCKSS (Controlled Lots of Copies Keeps Stuff Safe) Archive is a not-for-profit, dark archive, that preserves digital scholarly materials for the very long term, through a global and geopolitically distributed network of archive nodes. Founded by the world's leading libraries and publishers, the CLOCKSS Archive has achieved a unique consensus among publishers, who agree to make their content available for free in the case that they can no longer supply it. CLOCKSS is governed transparently and democratically by all participants and represents the shared values of the entire community.

Ingest and preservation workflow

The CLOCKSS Archive ingests and preserves the publisher's precise original artifact (both presentation and source files) in 12 archive nodes around the globe. Using the award-winning LOCKSS technology, content is preserved at the bit level. The globally and geopolitically diverse distribution of archive nodes protects the content from man-made and human misfortune. Format migration techniques ensure that the most up-to-date technology is used when required to make the content available to readers.

Library access to content

When content is not available from a publisher (a "trigger event"), CLOCKSS makes it freely available to everyone on the web, under a Creative Commons license. All libraries around the world will thus have access for free, obviating the cost and complication of authentication and authorization. CLOCKSS guarantees that open-access content remains open access after a "trigger event", as well as subscription content.

Auditing of content, policies and procedures (both internal and external activities)

Audits happen at many levels. INTERNAL: The CLOCKSS Archive uses the LOCKSS open source software, an award-winning preservation protocol that ensures the authenticity of preserved content at every level from the bits, to file formats, to human error and malfeasance. The CLOCKSS Archive Executive Committee and the Co-Chairs of the Board meet regularly to review finances, policies, and procedures with the Executive Director. The CLOCKSS Board of Directors meets regularly as part of routine governance and development processes. EXTERNAL: The Archive technology adheres to the security standards of the U.S. Federal Government. The Center for Research Libraries conducted an audit of CLOCKSS in 2013-2014. The CRL certification panel concluded that CLOCKSS can be recognized by its designated community as a trustworthy repository. The panel gave CLOCKSS its highest rating for Technologies, Technical Infrastructure, Security. And in 2018, CLOCKSS was the first archive to be re-certified by CRL, and the score for Organizational Infrastructure was upgraded to the highest score. CLOCKSS has the highest cumulative score of any CRL-certified repository. See http://www.crl.edu/reports/clockss-audit-report

Overview and background

The Global LOCKSS Network preserves today's e-journals and e-books for tomorrow's readers. The Global LOCKSS Network is a proven preservation approach that uniquely empowers both libraries and publishers. It enhances a library's value by restoring library collections via a locally installed "LOCKSS box", essentially a digital bookshelf. Payments are separated from access and perpetual access is guaranteed. The Global LOCKSS Network enhances a publisher's value by preserving the original published artifact (what the readers see), including branding and historical context and underlying files as supplied. It protects a publisher's business model by driving all reader traffic to their web site. The Global LOCKSS Network is administered and managed by the Stanford University Libraries LOCKSS Program. See the LOCKSS Program website for additional information, http://www.lockss.org/lockss/Home

Ingest and preservation workflow

The Global LOCKSS Network protects digital content against a wide range of technical, social, and management threats. The content and associated metadata are ingested and thoroughly tested to ensure the content's authenticity. The Global LOCKSS Network is format agnostic, with a proven file format migration framework to ensure content remains accessible and useable. The material is preserved for the long term in a robust fault- tolerant network. See the LOCKSS Program web site, "How It Works," for additional information, http://www.lockss.org/lockss/How_It_Works

Library access to content

Authorized readers at participating institutions access content from an institution's LOCKSS box whenever the content is unavailable from the original publisher's web site. The Global LOCKSS Network provides continual access as well as perpetual access. The LOCKSS system uniquely preserves the content at the original URL with all original bibliographic metadata so that content can be easily located by web search engines, library catalogs, and all bibliographic services. Integration with Open URL link resolvers such as SFX, 360 Link, and Cufts is underway. See the LOCKSS Program website for additional information, http://www.lockss.org/lockss/How_It_Works#Providing_Access

Auditing of content, policies and procedures (both internal and external activities)

The LOCKSS Program's Global LOCKSS Network builds and uses open source software, enabling the community to quickly identify and correct inevitable software bugs. An award winning preservation protocol ensures the authenticity of LOCKSS preserved content. As required for systems, which are tamper evident, the Global LOCKSS Network is preserving at least seven copies of the content, with each copy held in an independently administered LOCKSS box. The Library of Congress and the LOCKSS Program staff have completed the Certification and Accreditation process under the Federal Information Processing Standard for categorizing security risks of federal information and systems (FIPS 199). A CRL TRAC test audit of LOCKSS can be found at http://www.crl.edu/content.asp?l1=13&l2=58&l3=142&l4=71 For more information, please see: http://www.lockss.org/lockss/How_It_Works#Auditing

Overview and background

HathiTrust is an international partnership of academic and research institutions (see http://www.hathitrust.org/community for a list of all partners). The institutions own and operate a collaborative digital repository, created to preserve and provide access to millions of volumes digitized from their library collections and other sources.

The digital repository is designed according to the framework for Open Archival Information Systems (OAIS) to fulfill ingest, archival storage, data management, and access functions for large (millions of volumes) amounts of material. This design is realized within the context of community-wide standards and criteria for Trustworthy Digital Repositories.

Ingest and preservation workflow

There are two parts to repository ingest: ingest of bibliographic data and ingest of digital content files. Bibliographic data is used in content discovery and rights management strategies. Content files include a limited number of standard, open, image and textual formats that undergo rigorous validation and integrity checks on ingest.

The repository comprises two synchronized instances of active storage with wide geographic separation, and encrypted tape backup with 6 months of previous-version retention in a third location. All storage is physically secure, locked in racks within data centers that are accessible only to authorized personnel. See http://www.hathitrust.org/technology for more information.

Library access to content

HathiTrust offers viewing, downloading, and bibliographic and full-text searching options for public domain and open access content in the repository. Bibliographic and full-text searching options are available for in copyright volumes. Specialized features are also available to facilitate access by persons who have print disabilities, and allow users to gather subsets of the digital library into personal collections that can be searched and browsed. See http://www.hathitrust.org/access for more information.

Auditing of content, policies and procedures (both internal and external activities)

HathiTrust conducts regular audits that verify the integrity of preserved files, and the correspondence of digital files to both bibliographic and rights information, and information stored in indexes used for bibliographic and full-text search. Active use of content for display and searching purposes provides an additional check on content integrity.

HathiTrust was certified in 2011 by the Center for Research Libraries for compliance with the Trustworthy Repository Audit and Certification criteria (see http://www.hathitrust.org/trac).

Overview and background

The Library of Congress is the United States' oldest federal cultural institution and serves as the research arm of Congress. It is also the largest library in the world, with millions of books, recordings, photographs, maps and manuscripts in its collections. The Library's mission is to support the Congress in fulfilling its constitutional duties and to further the progress of knowledge and creativity for the benefit of the American people.

In 2010, the Copyright regulation governing mandatory deposit was revised to allow the Library to demand serials published online only. As a result, the Library has been building a growing collection of eSerials which has been increasing exponentially.

Ingest and preservation workflow

The Library receives content as network transfers and on physical media. For both mechanisms the Library has put in place a series of workflows, some media-based and some project-based. The workflows are instantiated as XML and operated through a workflow engine in the Library's Content Transfer Services (CTS). Each workflow includes human-operated and machine-operated steps, and includes copying onto Library hardware, malware scanning, fixity checking, fixity creation if none were provided, and copying to the appropriate Library server location, including processing space, delivery space, and long-term storage. Appropriate inventory records and actions/events are recorded.

Library access to content

This digital content is available to authorized users onsite at the Library of Congress.

Overview and background

Scholars Portal was founded in 2002 by the Ontario Council of University Libraries (OCUL) in cooperation with the University of Toronto Libraries. Our mission is to provide shared digital services to Ontario’s 21 university libraries. Scholarly materials licensed by OCUL members are loaded on the Scholars Portal Journals platform, which provides perpetual access to the content and supports its long-term preservation. In 2013, Scholars Portal Journals was certified as a Trustworthy Digital Repository by the Center for Research Libraries.

Ingest and preservation workflow

Scholars Portal receives content directly from publishers. Upon receipt, the content and metadata is verified and then normalized, where appropriate. The files comprising every object in the repository are accounted for: file formats are identified, fixity values calculated and checked regularly, and significant events in the history of the object are recorded. Scholars Portal closely tracks its community’s needs to ensure that the materials in the repository are usable, and will transform files to new formats if they risk becoming unusable by OCUL members. Please visit our Trustworthy Digital Repository documentation for more details on our preservation workflow.

Library access to content

Scholars Portal is OCUL's “light archive” for scholarly content. Content deposited in the repository is made available immediately to the OCUL members with a valid license. This approach allows students and researchers at participating institutions to search and access their institution’s licensed content through Scholars Portal Journals in addition to the publisher interface. One of the strengths of this preservation approach is its transparency: our data is continuously verified by our users, making for a high-quality archive.

Auditing of content, policies and procedures (both internal and external activities)

Scholars Portal is directly answerable to the directors of the 21 OCUL libraries through a series of committees that guide specific aspects of the repository's operation. These representative committees are composed of experts from the OCUL community and ensure that Scholars Portal operations are directly meeting the needs of the community.

In addition to verification of file validity and regular verification of fixity values, Scholars Portal's role as a light archive means that patrons at OCUL institutions are constantly reviewing the content in the repository. Scholars Portal provides numerous feedback mechanisms to report missing or corrupted content, and this level of use ensures that the repository always has a view of the content's usability.

The policies and procedures guiding the preservation of content in Scholars Portal Journals were certified as a Trustworthy Digital Repository by the Center for Research Libraries in 2013 and our documentation is available online.

The Swiss National Library collects and archives everything about Switzerland; everything which is published in the country or written by Swiss authors. Every publication, from Swiss daily newspapers to novels, from documentaries and yearbooks to official publications and geographical maps.

The mandate of the Swiss National Library about collecting, listing, preserving as well as making available Helvetica to the public is described in the law on the Swiss National Library SR 432.21. The mandate includes digitally born publications such as, for example, e-books, e-journals and websites.

e-Helvetica is the Swiss National Library's service working on safeguarding Switzerland's digital cultural heritage over the long term and ensuring that it remains accessible to future generations. The goals of e-Helvetica are to create the frameworks for collecting, recording, making available and sustainably preserving electronic Helvetica and to establish digital archives for electronic publications. As well as constructing a technical platform for long-term archiving, cooperation with various partner institutions is essential to the development of the collections.

The Swiss National Library's digital collections contain today commercial publications, monographs, periodicals, websites, theses and official publications. Websites and theses are included in cooperation with partner institutions.

Ingest and preservation workflow

Ingest handles the reception and the automated preparation of data for long-term archiving. The Ingest process takes over publications intended for the archives from their producer and reviews, prepares and, finally, files them away along with the relevant metadata. In addition, access systems such as the catalogue of the Swiss National Library are updated with information concerning publications newly received by the archives.

The Ingest process comprises a whole series of individual automatic steps:

 

• Data acceptance
• Unpack/Decompress data
• Unpack/Decompress data
• Import electronic publications
• Quality assurance
• Version management
• Persistent Identifier / URN
• Checks, completeness
• Feed into systems
• Cleanse

Library access to content

A full-text search (Solr / Lucene ) across all the Swiss National Library's digital collection is available in e-Helvetica Access. The advanced full-text search allows filtering of results by books, journals, websites or university publications. Other filters are also available in the advanced full-text search e.g. language, year, Dewey. Full-text search results may also be refined through facets e.g. place of publication, year of publication, language, type of publication and availability.

Access rights to digital publications are also managed in e-Helvetica Access. A digital publication's accessibility is indicated via a traffic light display: green indicates that it is freely available for consultation, orange that there are restrictions applied (on-site access at the Swiss National Library only) and red that it is not available.

Metadata search is still carried out in the library's catalogue, Helveticat. Links in the Helveticat records connect directly to the appropriate title in e-Helvetica Access.

Auditing of content, policies and procedures (both internal and external activities)

The Swiss National Library is building a new Repository that will replace the existing storing system. Information on auditing, policies and procedures will be provided as soon as the new Repository is in place.

Today the Swiss National Library uses a redundant NAS system (Network Attached Storage) for long-term storage of its digital publications. The two NAS filers are situated at two locations in Bern. Automatic data replication between the two systems ensures that stored data are available in their entirety at both locations. In addition, a tape drive at the secondary location is used to create a third copy of the data on magnetic tape. This third copy is stored separately. The Federal Office of Information Technology, Systems and Telecommunication (FOITT) operates the storage system.

Overview and background

Making knowledge and information freely available, sharing it and preserving cultural heritage: TIB – Leibniz Information Centre for Science and Technology and University Library provides science, research, industry and business with literature and information – in both printed and electronic form. The library is committed to openness, open access to information, publications and scientific data: it aims to make information and knowledge more easily accessible, more transparent and better reusable.

As the German National Library of Science and Technology as well as Architecture, Chemistry, Computer Science, Mathematics and Physics, it holds a unique collection of science and technology worldwide, including audiovisual media and research data.

As a research institution, TIB is continuously expanding its role as the German information centre for the digitisation of science and technology. It conducts applied research and development to generate new services and improve existing services. Its research focuses on Data Science & Digital Libraries, Scientific Data Management, Non-Textual Materials, Open Knowledge, Open Science and Visual Analytics.

TIB has the task of ensuring long-term access to its collections. The task of digital preservation is derived from this and is documented in the TIB Strategy. Serving as archive for DEAL collections, TIB ensures the access to published content in case of a trigger event. TIB hosts and maintains a centrally operated digital preservation system, details of this are outlined in TIB's institutional Preservation Policy. 

TIB is a public-law foundation of the Federal State of Lower Saxony. The library is a member of the Leibniz Association.

Ingest and preservation workflow

TIB operates an OAIS-compliant digital archive and uses common standards. Different workflows are configured for the various object groups in the digital preservation system (Rosetta). TIB records and reviews metadata (descriptive and legal metadata) during the Pre-ingest-phase. Intellectual entities (IE) are enriched during ingest with technical, descriptive and structural metadata. The Rosetta data model is based on PREMIS; an Archival Information Package (AIP) in Rosetta is identical to an IE as defined in the PREMIS data model and described by a METS file (ie.xml).

Various processes are performed in the validation stack during ingest: Format identification, format validation, three checksums, virus check, extraction of technical metadata, validation of the METS file. As soon as the ingest process for a Submission Information Package (SIP) is initiated, all modifications to the SIP/AIP and its metadata are recorded by the system as DNX elements in the event metadata.

A full documentation of TIB’s digital preservation workflows is available in the publically available TIB Digital Preservation Wiki.

Library access to content

TIB’s collections are available via the TIB Portal as well as via other access platforms. Open access content or openly triggered content is freely available and searchable via TIB Portal under the Libraries Terms of Use.

TIB operates what is known as a “dark archive”, and by doing so pursues the concept of separating the archive from the search function; searches always take place via a presentation platform.

Auditing of content, policies and procedures (both internal and external activities)

Procedures in TIBs Digital Archive are framed by polices, ranging from the overarching Digital Preservation policy to collection and function based policies. In addition to an extensive policy framework which serves the purpose of ensuring procedural accountability at different levels, TIB firmly embeds regular external audits via certification as a trustworthy digital archive into active digital preservation practice.

TIB’s digital archive has been awarded the nestor Seal for trustworthy digital archives in 2022. Go to report (in German only) / Go to application form (in German only).

Based on a self-assessment, TIB’s digital archive was awarded the CoreTrustSeal in 2020, which certifies the archive’s trustworthiness. Previously, TIB's digital archive was awarded the nestor Seal in 2017, and the Data Seal of Approval in 2015.

TIB is the only digital archive within Germany that certifies against both, CoreTrustSeal and nestor Seal regulary

Overview and background

The ZBW – Leibniz Information Centre for Economics is the world’s largest research infrastructure for economic literature, online as well as offline and serves as National Library for Economics in Germany.

The ZBW has the mandate to ensure the permanent and sustainable availability of its holdings. This applies in particular to digital publications, which are permanently stored in the long-term archiving infrastructure provided for this purpose.

As an infrastructure institution, the ZBW negotiates and manages digital products in consortia at national level, including transformation agreements. This activity results to a special responsibility for the permanent availability of licensed electronic publications. The ZBW fulfils its obligation by archiving and long-term preservation of these products.

Ingest and preservation workflow

Generally, content is transferred into the Digital Long-Term Archive once processing of the digital objects, including metadata enrichment, is concluded. For continually growing collections dedicated software ensures that new content is transferred into the Digital Long-Term Archive on the same day.

The ZBW uses the Digital Asset Management and Preservation Software Rosetta by ExLibris for its digital preservation. By means of Rosetta and its integrated workflows, objects are transformed into an archive package, including all the metadata required for a sustainable usability of the object. If needed, the files in an Archival Package are transferred into file formats that are better-suited for long-time-availability. Please visit our https://exlibrisgroup.com/products/rosetta-digital-asset-management-and-preservation for more details on our preservation workflow.

Library access to content

The content that the ZBW provides is accessible via special representation platforms, operated by the ZBW. There are two platforms for different purposes:

• (1) EconStor : an Open Access publication server for literature on business and economics
• (2) ZBW Digital Archive : it contains born digital material from the domains of business and economics.The ZBW Digital Archive is divided in two sections:

   

  • (a) The content of one section is accessible in open access or restricted access via EconBiz, the Discovery System for business and economics of the ZBW.
  • (b) The content of the other section is in closed access and keeps publications for which the ZBW has the right and/or the duty for archiving.

Access to the preserved content is granted according to criteria set out in the licence agreements. These criteria are defined as trigger events. As a rule, access can be granted if the content can no longer be made available via the publisher's or a provider's platform. In other cases, the content may be made available after a certain period of time (moving wall). Access to the preserved content is granted to Authorised Users as defined in the licence agreements.

The Digital Long-Term Archive (based on Rosetta) is a dark archive whose sole purpose is to guarantee the long term availability of the objects stored in it.

Auditing of content, policies and procedures (both internal and external activities)

Since 2010, the ZBW has been operating a cooperative digital preservation system. We develop manual and automated workflows for the ingest of our digital holdings into the system and for the necessary adaptions of digital objects within the system.

Our growing experience and continuous exchange with experts in the field enables us to adapt our workflows ever more efficiently to our particular needs. Cooperations in national and international networks are highly important to us. Thus, the ZBW is an active member of the nestor network and the Open Preservation Foundation.

In 2017, the ZBW received the German nestor Seal for Trustworthy Digital Archives (certification based on the DIN 31644 norm). In 2015, the ZBW received the Data Seal of Approval. The ZBW has implemented procedures, policies and workflows to ensure long-time-availability. They are described in detail in the document "Risk Management and Preservation Planning in the Digital Archive of the ZBW" which can be found under the following URL: https://www.zbw.eu/en/about-us/key-activities/digital-preservation/risk-management
