Much of the time you will use Library Search to find ebooks and journal articles, however there are many types of sources (for example statistics, audiovisual, newspaper articles, case studies etc, government reports etc.). Many of them you will find on Library Search but sometimes you may wish to look at a specific subject database or you may be looking for a type of source that is only available directly on a subject database. 

Liaison Librarians at University of Sunderland have created Subject Guides which help you understand what resources are available for your subject, and provide guidance on how to access them.
