In 2015, the University of California Libraries adopted a new, coordinated approach to consolidating and preserving print journal backfiles.

Under the Journal Archiving Campaign Service (JACS), UC Libraries deposit print journal backfiles in a coordinated fashion each year to the Regional Library Facilities. A defined title list is prepared by the Shared Print Strategy Team and publicized by the Shared Print team at the California Digital Library (yearly for JACS 1-6, every two years starting in JACS 7&8), including titles from multiple shared print programs (e.g. JSTOR, IEEE, WEST) and title nominations from bibliographers via the CKGs. Campuses can contribute all holdings for the specified titles, without reviewing for existing RLF holdings. RLF staff receive holdings from multiple campuses, remove duplicates, accession a single complete copy for long term retention, and disclose UC’s retention commitment in union catalogs, including OCLC. For each title, a single shared print archive is disclosed and stored for long term retention and access.
