Search Tips

If you know the exact title you're searching for, it's a good idea to search the title in quotation marks (as long as you're sure you have it right!).


  • "of mice and men"
  • "gaudy  night"

When searching by author, search by "last name, first name" or "first name, last name."


  • Steinbeck, John
  • Dorothy Sayers

By default, WorldCat Local automatically ANDS your terms and searches for records that contain all of the terms in your search. Boolean operators should always be entered in ALLCAPS.

Operator Search Example Finds...
+ women + work + 20th century

AND women AND work AND 20th century

Same as the +; finds records that contain the words women, work, and 20th century.

OR nutrition OR "food science"

Records that include the word nutrition OR the phrase "food science." The OR operator is used to expand your search results.

NOT paris NOT fashion

Records that have the term "paris" but not "fashion". Used to exclude a term from your search results.

- paris - fashion Same as NOT. Finds records that have the term "paris" but not "fashion".

WorldCat Local does not automatically search for plurals or alternate endings. To make a search more comprehensive, truncate words using an *asterisk* . This technique allows you to find any word beginning with a designated root word.
