I found this on-line library of antiquarian Hermetic books from a Dutch Library in Amsterdam, 'EMBASSY OF THE FREE MIND'. Most of the books go back several hundred years.
If you can read old foreign typeface in various languages, including Latin, then you'll be okay. If not, well, its interesting all the same.

If you keep scrolling down, you will come to more books. There are about three thousand of them.
