Start by looking for books in the ONU library by using POLAR. If you don't see what you need, try searching the OhioLINK catalog to see what other libraries have. OhioLINK books take 3-5 business days to arrive, so plan ahead.
You can search by keywords and subject headings in Heterick Memorial Library's catalog. Keyword searching is better for broad searching and for when you are beginning your research. Subject searching is better for narrower searches.
