8. Searching the Library Catalog: Subject Searching

Subject headings are a form of controlled vocabulary. Most library catalogs, including the OSU Library Catalog, use very specific subjects called Library of Congress Subject Headings.

Subject terms are helpful in situations such as:

Often, the easiest way to find subject terms is to do a keyword search and look at the subject terms in records for items that are good matches for your topic.

Try this strategy to find useful subject headings. Remember it by thinking of the letters KISS:

  1. Keyword search your topic
  2. Identify a relevant item from the results
  3. Select subject terms relevant to your topic
  4. Search using these subject terms

The OSU Library Catalog has its subjects listed in two places when viewing a catalog record:

 

Full Record tab
Find Similar Items tab

 

You can also try to do a subject search, but remember that the terms entered are controlled vocabulary, so you may not find results on your first try (some, but not all, terms will refer you to the proper term to use). Most terms have many subheadings, separated by --. These can have further subheadings.

An example of a very long one:

Great Britain -- History -- Anne, 1702-1714 -- Poetry -- Early works to 1800

Searching for a single term as a subject, if successful, will usually give you a screen with links to related subjects, items with only that word (no subheadings) as a subject, and a list (perhaps several pages long) of subheadings.

Example (subject search for beetles, first 10 lines):
