Paper Print Archive Registry (PAPR) is a registry that supports archiving management of serial collections by providing comprehensive information about titles, holdings, and archiving terms and conditions of major print archiving programmes. PAPR includes:

  • A searchable database of print archiving programmes
  • Downloadable reports of titles and holdings for participating print archiving programmes
  • The display of title and holdings information from participating print archiving programmes

These programmes include the Law Library Microform Consortium (LLMC), CRL’s JSTOR archive, Portico, Western Regional Storage Trust (WEST) and CLOCKSS. The current manifestation of PAPR serves as a data analysis system for the WEST project and uses standards developed by the OCLC print archives disclosure pilot project to transmit data via the MARC field 583. Further development of PAPR will address additional functional, data and user needs. The knowledge base and tools, including PAPR, will augment existing CRL services and activities that support the strategic management and development of collections at the local and regional level.

The California Digital Library (CDL) served as development partner for PAPR. Additional advisory services were provided by CRL consultant Lizanne Payne and Ithaka S+R. Development will continue in order to serve the ever expanding needs of the community.

Harvard Depository

The Harvard Depository is Harvard University Library’s archival media storage and retrieval facility. The climate-controlled Depository is a critical resource for students, faculty, staff, and researchers across the University. The off-campus facility provides a strictly regulated media preservation environment, precise inventory-tracking controls, efficient online retrieval ordering, and dependable overnight delivery of materials requested from storage.

The mission of the Harvard Depository is to promote effective use of space on the Harvard campus and the retention of financially and historically valuable resources by providing a secure, reliable, and cost-effective archival environment for the storage and retrieval of primarily paper-based materials. Acetate-based film is also suitable for Depository storage.

Anyone with a valid Harvard ID may use Harvard University’s HOLLIS catalog to request the retrieval of most library materials stored at the Depository.

file000463686432The Research Collections and Preservation Consortium (ReCAP) is located at 400 Forrestal Road, on Princeton University’s Forrestal Campus in Princeton, New Jersey. ReCAP is a high-density, environmentally-controlled shelving facility jointly owned and operated by Columbia University, The New York Public Library and Princeton University.

ReCAP was designed and constructed to provide high-density shelving for library items, an excellent environment for preserving items and an inventory and retrieval system for easy and sure access to items for library users.

ReCAP’s environment is ideally suited for the shelving of all low use items, paper based and sensitive media formats. Most individual items are sorted by size and placed in open-top trays which are stored on an appropriate-sized shelf, in order to store the maximum number of items in the minimum floor area.

ReCAP’s five modules can accommodate approximately ten million volumes using a high density shelving system. The sophisticated inventory control system keeps track of item locations and produces picking lists for requested items. Items housed at ReCAP will be identified in the local catalogs with a direct web link to a request form. After a request is received, items will be delivered next day to consortium members.

The Northern Regional Library Facility (NRLF) is a cooperative library storage facility, the first of its kind in California. It is owned and operated by the University of California and is located on the grounds of UC Berkeley’s Richmond Field Station. The 98,000 square foot main building was completed in 1982; an 84,000 square foot stack annex was completed in 1990; and a 67,000 square foot storage module, as well as a new reading room were added in 2005.

The Facility offers high density, low cost housing for infrequently used library materials belonging to northern California libraries. At this time, depositors to NRLF are libraries on the University’s Berkeley, Davis, Merced, San Francisco, and Santa Cruz campuses, and the California State Library.

Established in 1987, the Southern Regional Library Facility (known as the SRLF) provides space for University of California library materials, archives and manuscript collections.

Utilizing high-density shelving, the collections are stored in a climate-controlled environment that is designed to preserve the collections.

The TriUniversity Group of Libraries (TUG) is a unique example of administrative co-operation among the Libraries of three Ontario universities; the Universities of Guelph and Waterloo, and Wilfrid Laurier University. Informal co-operation among these three has been in place for nearly thirty years; however in the past decade, rapidly advancing technology has enabled co-operation at a completely different level, and the result has been a slightly more formalised agreement to work together for mutual benefit.

file2551245588682PASCAL, the Preservation and Access Service Center for Colorado Academic Libraries, is the state-of-the-art high density library storage facility located on the new Anschutz Medical Campus. Operating since March of 2001, The Health Sciences Library shares PASCAL with four other academic libraries: Norlin Library of CU Boulder, Auraria Library, and the Law and Penrose libraries of the University of Denver. Health Sciences staff member, Michael Kelty, is the on-site manager of PASCAL.

Based on a design pioneered at Harvard University, PASCAL can hold 1.6 million volumes in under 10,000 square feet of space with the possibility of adding four more modules of equal size in coming decades. The building is climate controlled with year round temperatures averaging 55 degrees and 35% relative humidity. The sculpture in front of PASCAL is an original creation by Colorado Springs artist, Bill Burgess. Inspired by the ”educational role played by our libraries”, Burgess titled his work, ”Aspire.”

Currently, volumes eligible for storage are older research materials that have value but are in low demand. All volumes are sorted and stored by size in cardboard trays on 30-foot high shelves identified by bar-codes. Individual library catalogs indicate if a particular book has been moved to PASCAL allowing patrons to make requests via their own library. PASCAL personnel make every effort to deliver items to requesting libraries within 48 hours.

MLAC (Minnesota Library Access Center) is a high-density storage facility for Minnesota libraries that stores and makes available important but little used books. Unlike a library which shelves items either by subject or alphabetically by title, MLAC shelves items by size. The goal is to shelve at the highest density possible to maximize space usage.  Because the facility’s shelves are 17 feet tall, books are retrieved by trained staff on forklifts. The collection is closed to the public. All items in MLAC are listed in MnCAT, the University of Minnesota’s online catalog along with links to request retrieval.

Shared High Density Library Storage Facility (Downsview 5)

Shared High Density Library Storage Facility. Academic research libraries across North America are striving to achieve the optimal mix of collections, spaces, and services that will best position them for the future. Having developed large and nationally significant collections over a period of many years, our five libraries feel acutely the competing pressures of collections and spaces. As members of the Shared Preservation Collection project, our libraries have come together to meet this challenge with the bold and innovative vision of a truly shared collection, moving our institutions beyond the usual space-sharing arrangement and providing all of our users with streamlined access to a wealth of scholarly resources. The most heavily accessed materials in our libraries will remain in close proximity to our user communities. Low-demand items from our collections may be transferred to a shared, de-duplicated collection housed at the University of Toronto’s Downsview facility. All items (journals and monographs) in the low-demand collection will be discoverable and can be requested in each participating institution’s catalogue. By bringing together expansive and efficient high-density storage, removal of duplicated works across our collections, and use of the existing transportation network and new models of desktop delivery, we will support the release of space for new purposes in each of our libraries. We see this as a winning combination that balances space and financial concerns with the assurance that low-demand materials from our collections remain readily available for research and study.

The idea of the “shared preservation copy” is one of the foundations of this project. By eliminating duplicate copies of low-demand materials from across our collections in favour of a single shared copy, we can focus our efforts on providing long-term access to research materials. Additionally, we can retain ownership of all previously-purchased materials while generating significant efficiencies of scale and cost savings compared to multiple individual storage locations at our individual institutions.
