I would be great to find some print books on your topics.
Google books has digitized millions of books from libraries and publishers. It makes selected preview pages available for many books (and the full text for fewer). It let's you keyword search inside books and see a bit of context on pages where your words appear.
You can search it directly, but Wikipedia often links here, too.
If you find a good book here, you can check if PCC Library has it.
