Abstract

ABSTRACT LibX (http://www.libx.org/) is an open source Firefox extension that provides direct access to library resources in multiple ways: through a toolbar, a context menu, and via cues that LibX places into web sites a user visits. A LibX edition integrates support for the resources to which a particular user community has access, including the library OPAC, databases, and their OpenURL link resolver. As one of its features, LibX supports the fast (one-click) retrieval of known items, such as research articles. This frequent task is automated by exploiting Google's Scholar service as a hidden backend that is used for searches. In this paper, we evaluate the effectiveness of LibX in retrieving known items that were listed as references in a sample of articles in four widely read journals. We conclude that LibX's matching algorithm can lead the user to an accessible copy of an item on average in 81% of cases with a negligible number of irrelevant items retrieved. As a result, LibX can dramatically reduce the time spent on known item searches.
