The number of scholarly e-journals has grown considerably in the last ten years, however many academic library budgets have not kept pace. To cope with this imbalance libraries have been looking for an effective way to analyze journal quality and use this information to make informed collection decisions. The California Digital Library (CDL) developed a value-based strategy to assess journals which is now used as a major part of the University of California's systemwide e-journal collection planning process. The value-based process is objective and quantifiable and is based on measures of utility, quality, and cost effectiveness, with a goal of alignment to UC's user communities and programmatic needs.

The strategy involves using objective metrics to calculate the value of scholarly journals and identify titles that make a greater or lesser contribution to the University's mission of teaching, research, and public service. A key aspect of this strategy is the use of the CDL Weighted Journal Value Algorithm to assess multiple vectors of value for each journal title under review. This methodology compares each UC e-journal title licensed for systemwide use against other UC-licensed titles within the same subject category according to a variety of objective value indicators, in order to arrive at a comparative value for each journal within the UC shared licensing portfolio. The current analysis covers over 7,600 journals. Individual journal value metrics can be compiled in order to assess the value of journal publisher packages and to compare the value of a journal publisher package to other journal publisher packages.

CDL recently completed an extensive evaluation of the algorithm. We gathered feedback and recommendations from a broad community including bibliometric scientists, library school faculty, librarians, economists, and statisticians in order to validate the algorithm's accuracy and reliability.
