摘要: The authors created a research method to identify local users’ needs and explored how well currently available e-book content might meet those needs. Using circulation records, interlibrary loan (ILL) requests, in-house use as gauge of patron demand during three-year period, the study compared these records offerings from major aggregators. resulting data were analyzed by subject publication date. found that was not uniformly distributed across disciplines more recent publications likely have equivalents. highest percentage equivalents for titles requested via ILL, suggesting this be best place begin collecting. results suggest e-books may only fraction monographic scholarly output libraries cannot yet rely on entirely supplant print, although coverage is growing dramatically.
