How not to measure ejournal usage

Rick Ralston, Assessing Online Use: Are Statistics from Web-Based Online Journal Lists Representative?  Journal of Electronic Resources in Medical Libraries, March 15, 2007.  Only this abstract is free online, at least so far. (Thanks to medinfo.) 

Many library Web sites feature hypertext lists of their online journals. This article explores the reliability of usage statistics generated by these Web-based journal lists. Reliability is assessed by comparing the number of journal title accesses from the list with the number of articles downloaded per title supplied by electronic journal vendors. The study includes 468 titles from three different vendors. While a correlation in use from the two different sources was found, this sample's usage counts from the online journal list were not accurate enough to use with cancellation decisions.
