Administrative Materials for Reporting University of California Library Statistics 2022-23 Data

The UC libraries have collected annual statistics for over 75 years. The statistics are defined by the libraries and managed by the California Digital Library (CDL) in partnership with each campus library.  Some data collected through the annual statistics process are also used by the UC Risk Management and Budget and Planning offices, both located at the UC Office of the President (UCOP). 

In 2022-23, the UC Libraries reviewed the data requirements and instructions for these statistics to determine how the new SILS environment (presently Ex Libris’ Alma and Primo) should be used at the network level to standardize and centralize data reporting. This work was carried out by the Alma Annual Statistics Analytics Project Team (AASA-PT), a representative team with members from all ten campuses and CDL. The core objectives for the AASA-PT were to establish Network Zone reporting that increases data accuracy and comparability across campuses, and reduces duplicative, manual and labor-intensive processes. To achieve these goals, AASA-PT developed a series of recommendations that were reviewed and endorsed by UC Libraries leadership (Council of University Librarians, Direction and Oversight Committee, and the SILS Leadership Group) in June and July 2023. A copy of the AASA-PT report and recommendations on the UC Libraries/UCOP annual statistics can be found on eScholarship.

Starting in summer 2023, the annual statistics will be managed through the following approaches:

  1. Network Zone reporting, co-developed by the AASA-PT in consultation with local and systemwide experts, will be generated by CDL and utilized for most print and all electronic holdings, as well as risk management and print circulation data
  2. Campus-based reporting will continue largely unchanged for intercampus and interlibrary loan data, digital collection statistics and specific special collections and archives holdings counts (e.g.,  manuscript units, pictorial items)

Campus-generated data are due to CDL by Friday, October 06, 2023. Please use the revised data schedules [xlsx] for campus data submissions.

Detailed instructions, outlining the approach for Network Zone reporting and instructions and guidelines for Campus-bsaed reporting, are available here.
