Catalyst and WorldCat can be used to search for archival material which has been published in books, which are more easily accessible than going to a physical archive.

Pair a subject heading(s) with subject keywords such as "sources", "diaries", "interviews", "pamphlets, "correspondence", "personal narratives", "archival resources". Some examples:

• south africa and history and personal narratives
• united states and relations and cuba and sources
• cold war and correspondence
• soviet union and revolution and pamphlets
