This panel reported on a large longitudinal study of the effect of discovery systems on online journal usage.
Many libraries have implemented discovery systems, placing a single search box on the library’s webpage. We have told our users that was the place to start a search–a paradigm shift. How has this affected journal usage?
The basic question: does implementation of a discovery service impact journal usage? This study focused on publisher-hosted journal content. Here is how web -scale discovery tools work:
It was assumed that the total search effort at an institution will remain approximately the same, provided the user base remains relatively constant. The results of this assumption are:
Some previous studies have indicated substantial increases in usage after discovery implementation, and some publishers report decreases usage of their content.
The study surveyed 20 US libraries and 1 each from the UK, Australia, New Zealand, and Canada. Data were reported in aggregated form. Discovery tools were the 4 major ones: EDS, WorldCat Local, Summon, and Primo. Data from 6 publishers, including over 9,000 journals, and over 140,000 usable observations. The source of the data was library’s COUNTER reports.
General results of the study were:
Observations from statistical analysis of the data:
- There are usage differences across libraries and publishers.
- Usage of all the discovery tools increased. Primo and Summon had higher usage increases.
- Discovery tools impact usage of different publishers differently.
- Impact of interaction between discovery tool and publishers is significant.
