| Abstract: | In the current environment of widely dispersed and disparate electronic data sources, collection managers increasingly need tools such as decision support systems to routinely perform common types of collection analysis: collection comparison, usage, package deals, and resource sharing. Four commercial decision support systems, Serials Solutions’ 360 Counter, Thomson Reuters’ Journal Use Reports, Swets’ ScholarlyStats, and Serials Solutions’ Ulrich's Serials Analysis System, are considered for their strengths in the above types of analysis and across five additional dimensions: Project COUNTER (Counting Online Usage of Networked Electronic Resources) reports supported, analysis tools, custom data sources supported, reporting features, and product support. Current issues and future trends are discussed. |
