Sorry, what's the issue with PDF/A? Since it's supposedly the 'archival' version, that's what I asked for; I wanted to maximize the lifetime of these things. What version of PDF should I be asking for? (I'm not doing the PDF'ing. The person who is is using Acrobat.) Are any other of the things I've scanned that aren't up for the same reason? List here (first two sections): http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/PDP-11_Stuff.html Please let me know, and I'll get them re-PDF'd into an acceptable form. Noel
