Ebook collection analysis: subject and publisher trends

an article by James Cory Tucker, (University of Nevada, Las Vegas) published in Collection Building Volume 31 Issue 2 (2012)


This paper aims to provide an assessment of an ebook collection in an academic library, and attempts to locate usage trends by subject and publisher.
The research was based on: three years of usage data from two e-book packages: NetLibrary and Ebrary; two methods of purchase: NetLibrary was a one-time purchase; Ebrary is purchased on a subscription basis. The research evaluated usage difference over time between the two packages and analysed subject and publisher usage.
The research found that Ebrary showed increased usage over time; NetLibrary demonstrated decreased usage; subject analysis showed ebooks in health sciences and hotel had highest usage; publisher analysis results illustrated the fact that five publishers had highest usage in both ebook collections.
Research limitations/implications
For circulation rate of each ebook package, two years of data were not available for Ebrary, resulting in incomplete comparison over three-year period between the two packages.
Practical implications
The paper assists in identifying usage patterns of ebooks across publishers and subjects; compares two different business models of obtaining ebooks; and helps with effective selection of ebooks to support teaching and learning.
Usage data over three years provided evidence to help libraries select a business model for acquiring ebooks; the research provides assessment of ebook collections to identify trends across publishers and subjects.
