To measure the value of print journals, librarians have gathered a range of
statistics and developed a variety of metrics. Similar work to assess the
value of e-journals has just begun. This article explores the usefulness of
available e-journal usage statistics and develops three metrics and three
benchmarks based on those metrics.
The proposed metrics build on earlier work that assesses the value of print
journals, although the earlier work is modified extensively to fit the e-
journal arena. The e-journal statistics and metrics are further transformed
to address a completely new area of application: the evaluation of
potential purchases. Statistics and metrics are used to build three
benchmark measures for assessing e-journal candidates for purchase. A
comparison of Science and Nature site licenses illustrates the utility of
the assessment benchmarks. The benchmarks, metrics, and statistics
developed here provide a reliable framework for assessing both current
collections and candidate collections of e-journals. Implications for
standards development are clear; content measures are desperately needed
for the development of an effective suite of e-journal statistics.
