Searching by Subject




|

Another way to search for a topic is by Subject. For more on the advantages and disadvantages of searching by keyword vs. subject, see

In many electronic databases, when you conduct a subject search, the computer searches a special list of terms called subject headings. Subject headings are terms which describe what an item is "about". A library item is usually assigned one or more subject headings.

Most academic libraries use the Library of Congress Subject Headings (LCSH). Consult LCSH to ensure the words you use for a subject search are valid subject headings.

For example, if you did a subject search using an appropriate SUBJECT HEADING such as "space colonies" you would find the following:

You searched for the SUBJECT: space colonies

Space Exploration is not used in this library's catalog.

Outer Space Exploration is used instead.

SEARCH for Outer Space Exploration.

You can also use a subject search to find items about people. Be sure to type in last name first, for example:
