High Quality Content by WIKIPEDIA articles! LibX is a free, open source scholars` extension for the Firefox and Internet Explorer browsers that lets people use services offered by their library. Users can search their library catalog(s) and databases through a search bar or through a context menu. The context menu is adaptive (changing depending on what the user selected) and configurable (allowing the user to include any configured resource). LibX supports the catalogs of all major vendors. In addition, any resource that can be searched using an http GET request can be included, similar to Firefox`s smart keywords.
