The online catalogue contains all recent books, but not all the older material. Many books on reading lists are kept in the Short Loan Collection on the Ground Floor, still arranged by the same classmarks. The detailed screen in the computer catalogue will tell you if one or more copies of that book are on Short Loan. If you are looking for a periodical article , search by periodical title in the computer catalogue.
Periodicals have classmarks, like books, and are arranged on the main floors by subject.
Recent, unbound parts are in the Current Periodicals Area on Floor 1. A number of heavily-used periodical articles are kept at the Circulation Desk on the Ground Floor. Videos of certain films are also available from the Circulation Desk. They are listed in the catalogue and you will need to ask for them at the Circulation Desk by the Classmark, eg. Videotape 287, Videorecording 18.
