Secondary Source: A publication that digests, analyzes, evaluates, and/or interprets the information in primary sources. A Secondary Source may also be a Peer Reviewed Source.

Many primary sources are published and cataloged just like book. You can use the library’s catalog or the OhioLINK catalog to find them. Some ways to help find those are:

1. Identify key players and search for them as authors. This will find papers, correspondence, memoirs, etc. Remember that government agencies and corporations may also be authors.
2. Do a keyword search using your topic and the words sources, diaries, letters, or correspondence (e.g. Great Britain and history and sources)
