Keyword searches look for resources using any words that describe your topic.
Now you can take the words from the list and combine them to search the catalog.
Put one word in the search box and search and see what you get. (Example: Oedipus)
To search for books and videos using keywords:
Don't put an entire sentence in the search box!
Start off slowly.
Put one word and then search.
Then add another.
This way if all of a sudden you don't get any hits, you know you should take the last word added and change it to something else.
