One good way to discover primary sources relevant to your research question or topic is to check the citations and bibliographies in books, articles, and dissertations related to your project.
You can search for all of these sources in Omni. Whether citations appear as endnotes or footnotes, they can be very helpful in leading you to primary sources found in archives, as publications, on microfilm, and online.
Bibliographies in books and dissertations often separate out lists of the primary or archival sources consulted.
