[alt-photo] Re: caseine patent

[Kees Brandenburg]

Hi Chris,

I think it was mentioned here allready but did you also check: http://www.camera-obscura.org

"www.camera-obscura.org is a digital library on the history of photographic techniques. Several thousand books from the public domain will be available soon online for free with the possibility of advanced search directly in the book content."

The patent number doesn't give any results but some more specific caseïne searches might do.
