Online Reference Sources

A guide to the variety of electronic reference resources available to the ESU community.

Welcome to the Online Reference Sources Guide

These pages serve as a guide to the variety of electronic reference resources available to the ESU community. Ebooks and databases are provided through subscriptions and can be accessed from any location and on any device. Simply log in using your ESU credentials when connecting from off campus. In addition, we have highlighted select reference sources that are freely available on the Web. Each of these sites has been reviewed by our librarians to ensure that it presents high quality, reliable, and credible information.

Although these lists of resources are not exhaustive, they are a good representation of the type and variety of electronic materials available for reference purposes. Other reference materials may be located through a search of the library catalog, Primo, and/or through a database search. Our Research Methods LibGuide serves as an excellent tutorial for conducting library research. If you do have any trouble finding the right reference sources for your needs or have questions about the materials, please contact a librarian. Librarians are available to meet with you in-person, as well as via chat, telephone, and emaill, and are always happy to provide assistance.

These pages will be regularly updated as new items are added to our collection.
