Mission
The primary exempt purpose of the organization is to develop and operate a library depository which will serve the educational and charitable purposes of the benefited institutions by enabling them to alleviate a critical shortage of depository facilities for the housing of books, manuscripts, microfilm and other archival materials, and to help preserve their collective library collections. The benefitted organizations are The New York Public Library, Astor, Lenox and Tilden Foundations, The Trustees of Columbia University in the City of New York, President and Fellows of Harvard College, and The Trustees of Princeton University.
