EAST currently retains approximately 6.2 million monographs (distinct OCLC numbers),  representing over 9 million holdings, and approximately 5,000 serials and journal titles, representing over 11,000 holdings. EAST is an accessible light archive with retained items held at the member institutions.  Retentions are disclosed in the members catalogs (see best practices for disclosure and a slideshow of catalogs)  and in the databases listed below.
