E-Journal Usage
Statistics for electronic journal packages licensed by the California Digital Library (CDL)
One indicator of a journal title's utility is how often is it used. This page provides links to e-journal usage information.
Some of the statistics listed on this site have been derived by publisher-supplied data. Whenever possible, the statistics are available on a title-by-title basis and refer to the usage of full text. Keep in mind that journals change titles, that some titles merge with others and some titles disappear altogether.
For questions about journal usage, contact Margaret Phillips.
