In addition, the article presents preliminary data regarding the use of bound volumes sent to storage and an overall analysis of this transformational project.     

Perfecting COUNTER and SUSHI to Achieve Reliable Usage Analysis

The Counting Online Usage of Networked Electronic Resources (COUNTER) Code of Practice and Standardized Usage Statistics Harvesting Initiative (SUSHI) are two standards whose successful adoption will greatly assist librarians in performing accurate and timely usage analysis of their online collections and thus make more informed collection management decisions. Variations in how these standards have been applied by content providers to their SUSHI and COUNTER implementation are currently impacting their widespread adoption. The standards themselves are not broken—what is needed is concise guidelines on their implementation. This column reviews some of the roadblocks that impede consistent implementation of these standards as well as proposes recommendations that could form the basis of a community profile for these standards.
