More Book And Research Resources

I came across some more useful information on research sources.  These are particularly of book sites that offer either online access to original documents you would never otherwise have the opportunity to see or to free pdfs of books and other documents, many of them downloadable.

As before, they’re on the [Public Domain->https://brucebird.com/website-content/public-domain] page although that’s not strictly true.

I really must make time to reorganise some pages here.
