Through the Lace Digest, I found yet another source for antique patterns that can be downloaded.  I won't vouch that it is a perfect site since the first one I clicked on seemed to have a password for unknown reason.  What is particularly interesting about this site is that in addition to English language publications a lot of the books are in French and German as well as a smattering of other languages.  The site is antiquepatternlibrary.org .
