In June 2000, Columbia University, Princeton University and The New York Public Library signed a partnership agreement to jointly construct and operate a remote high-density book shelving facility under the auspices ofThe Research Collections and Preservation (ReCAP) Consortium, Inc. ReCAP is a 501(c)3 corporation whose exempt purpose is to enable its members to "further their needs for library storage and retrieval and related collections and information management." 

Founding Executive Director Eileen Henthorne oversaw the development of ReCAP's operations and construction of its current physical plan, in four main phases: Modules 1-3 (2002), Module 4 (2005), Module 5 (2008), and Modules 8-9 (2013). The first four modules each consist of six aisles of shelving, with 37 ladders (vertical shelving sections) on each side of the aisle. Module 5 consists of 10 aisles with 42 ladders on each side. Module 8 and 9 are12 aisles designs, with 42 ladders on each side. Module 9 currently has 6.5 aisles built, with additional open space that will be built out in 2016-17. Initially, ReCAP provided intake of library collections and next-day delivery of materials to the partner's library sites. Starting in 2007, ReCAP started to expand its service to incorporate interlibrary loan and electronic document delivery, activities that now account for almost 20% of annual requests. 

Current Executive Director Jacob Nadal joined ReCAP in 2014 to oversee the development of the consortium's shared collections and cooperative print archives efforts, and expand the services provided from the facility. In 2015, the consortium started development of the software required to enable shared collections across multiple partner institutions with a fully integrated shared collection service planned for the Fall of 2017. This work was supported by a planning grant from the Andrew W. Mellon in 2012, and an implementation grant in 2015. The resulting "Shared Collection Service Bus (SCSB)" is a free and open-source platform that provide indexes of shared materials that can be integrated into library research discovery systems, and manages requests seamlessly for print or digital delivery across multiple library and inventory management systems.

At present, ReCAP has over 13 million library and archives items in its care, placing it among the largest single-site collections of research materials in the world. ReCAP fulfills as many as 250,000 requests each year in print or digital format, to its partner's libraries and through interlibrary lending, to researchers around the world.


ReCAP staff are employees of Princeton University, and our team includes several employees who have been with ReCAP since day one. We are proud to recognize their commitment to ReCAP and our partners, and we are grateful for the contribution they make every day:
