The Seismology of Google Scholar: Does Google Scholar rock your world?
San Francisco State University
From proxy data:
Use of Metalib decreased markedly when they proxied Google Scholar on their Databases list, set it up as an SFX source, and started teaching it in instruction classes.
In the "what a good idea" department:
SFSU proxied their Google Scholar link from their databases page so that Google would always recognize the user's IP address, even if they switched computers or were off campus.
They also have SFX data for Google Scholar as a source from 2006-2008. They show comparison tables for requests and clickthroughs:
2006 - EBSCO is #1, GS is #11
2007 - EBSCO is #1, GS is #3
2008 - EBSCO is #1, GS is #2
They used the Google Visualization Motion chart to display the change of 2008 monthly SFX request/clickthrough for the above two databases. Dumped their requests/clickthroughs into a Google Docs spreadsheet; the motion chart takes that obscure data and puts it in motion over time so you can see the changes. [JBK comment: Awesome.... What a great way to tell a data story.]
MetaLib - theirs is hosted by the CalState Xserver. They have only entered 4 DBs into MetaLib (Academic Search Premier, ERIC, JSTOR, ProQuest Newspapers). The real-time search appears as a delay to users - when they show it live, it's long (~40 sec for only 4 databases). The same search in Google Scholar takes only 0.09 seconds. Which tool is the user going to prefer?
They can't capture all proxy counts for Google Scholar, but do capture them all through their Fed search interface. In the time/use comparison they show, when they proxied Google Scholar and stopped teaching Metalib. They can't count all access to Google Scholar, but they know that use of Google Scholar is increasing, and use of Metalib is decreasing.
ILLiad and Google Scholar:
Once they added ILLiad as an SFX source, use of ILLiad via SFX jumped. Shortly after, they proxied GS and started teaching it. The percent of ILLiad requests coming from Google Scholar through SFX jumped from ~1% in 2006 to over 5% in 2008.
-SFSU treats GS as a regular database. Usage has increased and GS has become the most popular database in the library.
-Instruction has an impact on GS - Instructors feel it is a good resource discovery tool and have started teaching it.
-No dramatic decrease in the use of other DBs - GS co-exists with other DBs like Web of Science and Academic Search Premier
-Next steps might include replacing the Metalib link on their beginning search page with a link to GS.
