I picked up a cool little booklet today called "Ansco Formulas for B&W photography." I've started scanning them and made them into pdfs. If you have any interest in these, feel free to download them from this link:
If anyone finds this stuff interesting I can scan/post the rest of them. Actually, I've always thought APUG should have a library of all kinds of this stuff/manuals/etc. for everyone to reference. Anyway, hope you like them...I found it interesting.
