AND, OR, or NOT in the PSU Library Catalog

When using AND, OR, or NOT to refine your search, you will need to capitalize these words in order for them to work as Boolean operators. For example,

plastics AND oceans

wages OR paychecks

jaguars NOT cars

If you have any questions or need help, Ask a Librarian.

Use Wildcards

An asterisk (*) will replace any letter or set of letters in a word, so you can retrieve variants of the word in your search results.  


allerg* results - allergy, allergies, allergens, allergic, etc.

col*r results - color, colour
