At least once a year, we query the WorldShare ILL database and see how the trends in interlibrary loan are developing. We count titles a little differently than other lists. Rather than splitting into fiction/nonfiction we look at loan requests vs. copy requests (loans of an entire book vs. a request to copy a single article or part of a larger work). The list of top copy requests is, as you might expect, heavily weighted toward the medical, psychological and scientific realms. It’s the loan requests that are more interesting.
