Need for a quantitative tool to analyze cost and use data for electronic serials  Databases + E-journals 90%  E-journals up 9% from 07/08  Print budget halved in 3 years  2010 online serials usage: 2,106,913

4224 Subs (4060 Titles):  70% of e-journal budget (based on 08/09 exp)  50% total e-journal usage (based on 2009 JR1 reports)  18% of total e-journal titles (based on 08/09 ARL stats)  Total Cost/Sub rose 7.45%

 BUD (the Big Ugly Database)  Labor intensive  Large and unwieldy  Limited functionality  Serials Solutions’ 360 Counter  Left burden of data clean-up to the library  Costly for its purpose  Limited functionality

Tables, Queries and Relationships

Packages, Subjects and Titles

 Titles moved to the JSTOR Platform 2011  Price increased for 2011  Number of titles increased for 2011  Analyzed the 2011 stats for the 2012 renewal  2010 stats were complicated because of the platform change, but JSTOR created the JR1b  2011 stats were gathered for the Jan.-Aug. period

The database could already:  Provide Cost, Use and Cost/Use for  Provide LC subjects and impact factors for each title Additional work:  2011 JR1 for January-August (modified calculations)  Query A was limited by platform and 2011 use added  Query was exported to Excel for additional calculations  Summary data (totals, averages and medians by year)  Differences calculated from 2009 to 2011 as percentages
