Researchers apply vraious criteria to transaction log data to judge the success or failure of patrons? subject searches. Although researchers generally agree that most searches retrieving zero results are unsuccessful, the upper limit varies tremendously. For Larson, a ?successful? search retrieves between one and twenty records; for Hildreth, the upper limit is ninety, and for Yu and Young, the upper limit is one hundred.13 When success is defined in this ?numeric? way, analysis of transaction logs is a simple way to determine the frequency of successful subject searching.methoo.com
