Impact of research cultures on the use of digital library resources [PDF]

open access: yesJournal of the American Society for Information Science and Technology, 2007
AbstractCurrently, there exists little evidence concerning how various characteristics of research cultures are associated with patterns of use of electronic library resources. The present study addresses this gap by exploring how research‐group membership, across‐fields scattering of literature, and degree of establishment of research area are related

Ethnomethodological architectures: Information systems driven by cultural and community visions [PDF]

open access: yesJournal of the American Society for Information Science and Technology, 2007
AbstractAs networked digital systems are rapidly created and deployed, social, cultural, and community‐focused issues are often neglected. Indeed much research has focused on the “effects” these systems hold rather than viewing systems as tools to be designed given an understanding of sociocultural context.

open access: yesarXiv, 2000
Many text databases on the web are "hidden" behind search interfaces, and their documents are only accessible through querying. Search engines typically ignore the contents of such search-only databases. Recently, Yahoo-like directories have started to manually organize these databases into categories that users can browse to find these valuable ...
