Shared Print Program Phase 2

Phase 2, which began this spring, has the goal of securing retention commitments for print volumes corresponding to HathiTrust digital monographs that did not receive a retention commitment in Phase 1. We estimate that there are about 2.2 million HathiTrust digital monographs that did not secure commitments (about 20% of all HathiTrust digital monographs).

Phase 2 of the Shared Print Program officially launched in May 2018 and continued through May 2019. At the close of the phase, 1.5 million monographs were retained, which represents more than 750,000 individual titles. For this phase, 55 member libraries, including 27 new libraries, signed the Shared Print Agreement (MOU) which recognizes their continued support of the program by retaining shared print volumes for 25 years (through December 31, 2042).

This phase focused on a more thoughtful collective collection building analysis HathiTrust worked with Sustainable Collection Services (SCS) to analyze print holding records across shared print retention libraries and develop retention commitment lists. In June 2018, the HathiTrust Shared Print Retention Models Working Group was convened to develop the "retention models" (criteria for identifying and prioritizing print holdings to retain) for Phase 2. The Working Group proposed to use the model of retaining up to five of the same edition and work to aim for geographic distribution of proposed retentions based on the U.S. Census regions (see Phase 2 Statistics below for more information).

Phase 2 Statistics 

The majority of proposed retention commitments for Phase 2 are located in the Northeast U.S. Census Region.

Phase 2 Committed to Retain by Title

For Phase 2, the majority of titles have 1 to 2 libraries committing to retain (around 77%) them. This is equivalent to 639,808 titles.

Phase 2 Commitments by LibraryFor Phase 2, few libraries hold the majority of our commitments. 75% of all commitments for Phase 2 were made by 1 to 3 libraries.

52% of our Phase 2 Shared Print commitments are also committed at other shared print programs
