http://www.indiana.edu/~libpres/manual/mantoc.htmlThis is a pretty good place for information on some procedures used in restoration and conservation of paper items.
A lot of comic book restoration artists prefer to keep the exacts of their methods as trade secrets, the information is out there, you just gotta do the research, try searching for
paper restoration/conservation and certain procedures used (leaf casting, tape removal, etc), there are also a few books on the topic, but some of them can be a bit pricey.
Start small by picking up some cheap beaters and practice things like tear seals and minor inpainting.
