The following resources can be consulted for looking up definitions:
Dictionary - a reference book that lists terms
alphabetically. Each word has an entry giving spelling (including
alternative or variant spellings), pronunciation, part of speech
and meanings. Unabridged dictionaries are more comprehensive in
coverage than abridged editions.
Glossary - list of terms with their meanings
as applied in a specific subject field or discipline.
Thesaurus - an index of terms organised to show
relationships between concepts, eg. synonyms and antonyms, related
or associated words, broader or narrower terms. A thesaurus is
a very useful tool when searching for keywords related to an assignment
topic.
Some thesauri are published as a printed volume and will be held
in the Library's Reference Collection.
Theasuri are also available in searchable electronic format in
some databases. See Advanced Database
Searching.
