If the book you need is checked out, or if GTC doesn't own the book you want...Fear not! The first place to check is PASCAL Delivers. If PASCAL can't deliver, then use our Interlibrary Loan service.
Reference books are informative sources that give you background information on any topic you may be researching.
Encyclopedias, dictionaries, atlases, almanacs, and compendiums are all examples of reference books.
