WEST: Western Regional Storage Trust


Western Regional Storage Trust (WEST) logoThe Western Regional Storage Trust (WEST) is a distributed retrospective print journal repository program serving research libraries, college and university libraries, and library consortia in the Western Region of the United States. Under the WEST program, participating libraries consolidate and validate print journal backfiles at major library storage facilities and at selected campus locations. The resulting shared print archives ensure access to the scholarly print record and allow member institutions to optimize campus library space. This collaborative regional approach to managing library collections represents an important step, when joined with other initiatives, toward development of a highly trusted network-level shared print archive. To learn more about how WEST is working to maximize network-level analysis as well as regional and national collaboration, please see WEST Vision, Mission, and Guiding Principles and Value of WEST Infographic.
