Excellent suggestion. Thanks.
I've never looked into that sort of service before. Will research. I've got a couple of regular-use books that could use a hardening.
It's not going to be cheap, but there are, well there used to be services that did that for libraries. I have to assume they still exist.
My daughter's college job is with the local library -- after reading your reply I passed a request on to her to see if she could find any info on a small-quantity service.
