Search Options in the Collection

  • When searching the digital library collection, you can select Full Text & All Fields to search through all the text of all the volumes in the entire digital library, including book information such as Title or Author. Search results will list individual volumes within journals, so there will be more results. Using this type of search also allows you to add your results to a personal collection.

  • Narrow your search to only book information, such as Title, Publisher, and Author, by choosing All Fields indicated in the dropdown menu options. Search results will list journals but not individual volumes within each journal, so there will be fewer results. Using this search does not allow you to add your results to a personal collection.

Other Search Tips

  • Boolean Searching

    • Use AND and OR (capitalized) between words to combine them with Boolean logic: (heart OR cardiac) AND surgery will find works about heart surgery or cardiac surgery. 

    • When searching in Full Text & All Fields, use a minus (-) to remove words from the result, e.g., heart  -cardiac will find items containing the word heart that do not include the word cardiac. The word NOT is not available as a Boolean search term. 

  • Phrase Searching: Use quotes to search an exact phrase: e.g., "occult fiction"

  • Wildcards: Use * or ? to search for alternate forms of a word. Use * to represent several characters, and ? for a single character: e.g., optim* will find optimal, optimize or optimum; wom?n will find woman and women. Wildcard search is not available in Full Text & All Fields search.

  • If you would simply like to browse without entering a search term, you can enter * by itself.

Sorting Your Search Results

To sort your search results, please select one of the fields from the dropdown menu: for example, title, author, etc. If you search using “Full-Text & All Fields,” we don’t provide the sort capability because there are typically too many search results to make that feasible.
