What is a dictionary?
Dictionaries are alphabetical lists of words or
entries. They differ in the kind and in the 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 section of the Library.
Language dictionaries will be kept in the REF 400
section (Dewey class 400). REF stands for reference, i.e. a collection.
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. A dictionary of library and information science quotations is at REF 020.3.
Remember that material in the Reference section
of a Library can only be used within the Library, you can't take the
material out of the Library.
