Find a good secondary source, and work backwards. See what primary sources the author consulted, and search for them (you will probably find other relevant sources this way).
Think like an archivist. In archives, sources aren't organized by subject as they are in the library, but by the person, organization or group that created them. Start from what you know -- names of people, organizations, schools, or programs -- and do an internet search using that name plus a word like "papers" or "collection." Example: the Mary Lyon Collection
