Certain categories of books are for use only within the library and may not be borrowed. These include: 

  1. Reference Books: for e.g. dictionaries, encyclopaedias, and certain large or rare books.
  2. Course Reference Books: these are set aside at the request of the lecturers, or have been designated as recommended or required reading for a particular course and placed on the Course Reference Rack for the duration of the course (normally one term) for the sake of ease of access to the entire class.
  3. Periodicals: journals, magazines, and newspapers.
  4. Archival Materials: books marked with a letter A in red are very old, rare, fragile, or of historical importance, and are kept in a separate cupboard which is generally locked, but which can be opened at the discretion of the librarian on duty.
