Here are some additional ideas to get you started:
We suggest you learn some background on your topic and get ideas about what primary documents might exist. You should also consider what relevant keywords might be best to use in searches.
You can use the library's EagleSearch to search for items about related events, important names, legal actions, government documents, photos, interviews, and newspaper stories from the time period.
Citation chaining - look at references in relevant articles and books to see what original documents might exist. Then you can search for those. See our Citation Chaining guide for more information.
