Search Tips

Basic Search Tips

You can search DELCAT by simply entering keywords, as you might in any search engine. However, there are other strategies you can use if this approach is not working well for you:

  •     Use quotation marks to isolate specific names or phrases that you are seeking. 

"Abraham Lincoln"  (will exclude results like Lincoln, Nebraska or Abraham Heschel)

Using Boolean Logic

  •     Use the word AND (capitalized) to add search terms that make your search more specific.

"domestic violence" AND dating

  •     Use the word OR (capitalized) to search for synonyms or closely related terms at the same time.

adolescents OR teens

  •     Use the word NOT (capitalized) to exclude a term from your search and reduce the number of irrelevant results.

humor NOT vitreous

Expanding My Results

Expanding your search results will allow you to find items that are not owned by UD libraries. Items found by toggling on Expand My Results in the list of brief results will often require that the item be requested via Interlibrary Loan. When searching DELCAT and Libraries Worldwide, you'll find our collections, open access materials freely available online to everyone as well as materials not in the Library's collection.  In order to find a larger number of items that are not in the Library's collection, you'll need to toggle on Expand My Results.
