Bruce Heterick, Vice President, JSTOR, explained that JSTOR is a fairly unique content provider. Most of its content consists of back files of about 2,000 journals. JSTOR has an in-house analytics team to help understand their data in a better way.
Most access starts at JSTOR. Self-referrers include people linking within JSTOR. 5% of accesses come through the Serials Solutions link resolver. It is not possible to tell whether access comes through a discovery service or their link resolver. JSTOR now gets a lot fewer referrals from Google than previously because Google’s new ranking algorithm has affected publishers with pay walls. Link resolvers in Google Scholar drive a lot of traffic. Accesses through discovery services is small. One of JSTOR’s challenges is how to help people starting their searches at the JSTOR site have a better experience.
In 2012, usage for a small US institution dropped, which and was worrisome. In June 2012, the institution implemented a discovery service, causing the drop. JSTOR sent out a survey to institutions asking what discovery service they had and when they implemented it. Here are the results (2013 data also included).
Getting good data is hard, expensive, and requires negotiation.
Here are some initial conclusions from this study.
