Wendy, I know of a variety of products like this through doing archival
paper storage (I worked at a publishing museum) - the process is called
encapsulation, and it is used for preserving old papers without causing
permanent damage like lamination.

Or, you can visit their web site through this link:
This is not University's own URL, but you can get there through "Suppliers"
or "Conservation" - This is the "Book Arts Web" site and really nearly
unbelievable in scope and quality. (THANKS to whoever -I suspect Sandra B -
first posted the Book Arts Web site)
University has an Excellent catalog, - one of those things I think Every
Body Should Have - but don't bother requesting one by email, because you
will never get it (in my experience) - go with the toll free number.
They have been in business a long time, have lots of good things like acid
free tissue and UV filters to slip over different types of light bulbs.
