""A library database is an electronic catalogue or searchable index. We subscribe to several of them for you to use while you are a student or staff member of IT Sligo. These databases are very expensive and valuable resources so you should make the most of them while you are a student here. The full list of databases is available on our libguides website, and we have a useful guide created to help you with issues such as off campus access, linking, authentication problems and copyright information.
