Analysis of Static and Dynamic E-Reference Content at a Multi-Campus University Shows that Updated Content is Associated with Greater Annual Usage
AbstractA Review of:
Lamothe, A. R. (2015). Comparing usage between dynamic and static e-reference collections. Collection Building, 34(3), 78-88. http://dx.doi.org/10.1108/CB-04-2015-0006
Objective – To discover whether there is a difference in use over time between dynamically updated and changing subscription e-reference titles and collections, and static purchased e-reference titles and collections.
Design – Case study.
Setting – A multi-campus Canadian university with 9,200 students enrolled in both graduate and undergraduate programs.
Subjects – E-reference book packages and individual e-reference titles.
Methods – The author compared data from individual e-reference books and packages. First, individual subscription e-reference books that periodically added updated content were compared to individually purchased e-reference books that remained static after purchase. The author then compared two e-reference book packages that provided new and updated content to two static e-reference book packages. The author compared data from patron usage to new content added over time using regression analysis.
Main Results – As the library acquired e-reference titles, dynamic title subscriptions added to the collection were associated with 2,246 to 4,635 views per subscription while static title additions were associated with 8 to 123 views per purchase. The author also found that there was a strong linear relationship between views and dynamic titles added to the collection (R2=0.79) and a very weak linear relationship (R2=0.18) with views when static titles are added to the collection. Regression analysis of dynamic e-reference collections revealed that the number of titles added to each collection was strongly associated with views of the material (R2=0.99), while static e-reference collections were less strongly linked (R2=0.43).
Conclusion – Dynamic e-reference titles and collections experienced increases in usage each year while static titles and collections experienced decreases in usage. This indicates that collections and titles that offer new content to users each year will continue to see growth in usage while static collections and titles will see maximum usage within a few years and then begin to decline as they get older. Fresh content is strongly associated with usage in e-reference titles, which mirrors the author’s previous work examining static and dynamic content in e-monographs.
