Why am I not at all surprised??

Great work from everyone involved in getting this information out. Anything involved with copyright and archives can be a major pain to get through all the red tape.

Tech IB prints aren't like a regular print. They essentially have been finished photochemically so there's nothing that you can do with them after that besides screen the print or digitally scan it. They were made to last...and look brilliant. If scanned correctly, I don't think there's much to be done afterwards. Correct me if I'm wrong here.

Hmm...I've always wondered what materials RAH was referring to. I sincerely hope it wasn't the LoC.
