Understanding the information needs of large-scale digital library users

Abstract

This paper reports on the results of a comparative study of user search logs in two large-scale, domain-specific digital libraries functioning in the United States: the National Science Digital Library and Opening History. Results demonstrate varying levels of use of advanced search options and substantial differences in the search query lengths, search query frequencies, and distribution of search categories in queries. The empirical data on how the members of the target communities search can be used in deriving important information for domain-specific digital library developers' decisions regarding both the details of information organization and support of various search features.
