Reference resources are more than just old encyclopedias! Reference resources can be online, or in print, and are about more than just finding general information. Reference materials can be a great place to find in-depth historical information about a topic, definitions, and more. The ODU Libraries provides access to many subject specific reference resources.
To find reference resources in your research area, start with Monarch OneSearch, type in your topic, and then type in the type of resource your need. For example, you could try: dance AND encyclopedia (yes, we have one of those!)
