ReCAP, the Research Collections and Preservation Consortium, Inc., is a 501(c)3 not for profit corporation that preserves the collections of its member libraries and enable its members to share their research materials, so that be available to readers for into the future. ReCAP was incporated in the year 2000 to enable its members to "further their needs for library storge and retrieval and related collections and information management."

With over 13 million items currently in its care, ReCAP operates the world's largest library and archives preservation repository and provides daily print and digital delivery of these materials to its member libraries and to libraries around the world through interlibrary loan. The storage environment at ReCAP is highly optimized for preservation of library and archival collections. ReCAP's storage modules provide more than four times the longevity of conventional library stacks and its inventory control systems prevent any loss of materials. 

The ReCAP members are engaged in a major shared collections initiative that is identifying millions of items at ReCAP that will be kept in perpetuity and shared among ReCAP members and will enable the partners to cooperate on extensive collecting and preservation efforts for the printed record. The software that makes this possible is released under an Apache 2.0 open source license and the planning and policy documents are availabe under a Creative Commons license. 

ReCAP is committed to sustainable preservation in many ways: through its care of collections, its use of sustainble energy sources and maintenance of a conservation landscape, its cooperative business models, and through partnerships that explore opportunities to optimize and improve library collections managment.
