Using Eagle Library Search

Starting Your Research

Use ELS to jump-start your research

  • Get an overview of the number and types of resources available.
  • Get links to research starters, guides, and other background sources.
  • Have immediate access to full text materials and media.

In-Depth Research

Use ELS to take a deeper dive into your research project

  • Use limiters to select only scholarly articles.
  • Select source types as your project progresses. Do you need articles, books, or primary sources?
  • Select specialized databases to select more relevant materials.
  • Use advanced searching to refine your search, add terms, and use boolean operators. The Advanced search option appears underneath your search terms at the top of the result page.
  • Advanced searching also allows you to select field codes to narrow your terms to only certain elements of each entry, such as title, author, or subject terms.

Boolean Operators

Use ELS to Build a Precise Search Using Boolean Operators (and, or, not)

By default ELS searches for your search terms that occur somewhat close together (proximity). By using the Boolean operators -- and especially AND between your search terms and phrases -- you can make your search stronger and more accurate.

  • Use AND between your search terms to get all the items that match all your search terms and ONLY those, for example: social media and memes. You can also add AND and additional terms to narrow the search even more: social media and memes and regulation.
  • Use OR between synonyms or near synonyms to get all items that match ANY of the terms, for example: United States or USA or America.
  • Use NOT before a search term to get all results except those that match the term after NOT; for example: civil war not United States.

In addition, in ELS

  • Use quotation marks to use an exact phrase as your search term: "Painful Case" ; or "painful case" and Joyce
  • Use * to replace one or more letters at the end of a word: immigra* instead of immigration or immigrating or immigrant.
