What is a dictionary?

Dictionaries are alphabetical lists of words. They differ in the kind and in volume of information they hold. It is often necessary to consult more than one dictionary, and more than one type of dictionary.

Where to find dictionaries?

Dictionaries are reference works and are therefore normally kept in the Reference Collection in the Library.

Language dictionaries will be kept in the 400 section (Dewey class 400).

Subject dictionaries will be filed at the classification number for the subject, e.g.

• Dictionary of science = REF 503
• Dictionary of mathematics = REF 510.3
• Dictionary of physics = REF 530.03
• Dictionary of art = REF 703

Biographical dictionaries will be at 920, or alternatively with the subject the person is known for, e.g. engineering, medicine, etc.

Quotation dictionaries will be filed in the REF 808 class unless it is subject specific in which case it will go with the number for the subject, e.g. REF 300.3 SOC.

Social sciences quotations: who said what, when, and where / David L. Sills & Robert K. Merton, editors.

Remember that material in the Reference section of a Library can only be used within the Library. You may not take the material out of the Library.

Use the library catalogue (OPAC) to find a dictionary that meets your specific subject needs.
