I've got a very practical question for any of my friends who care to chime in with recommendations. I have a book with a badly broken spine and some pages threatening to come out. I wanted to find "rubber cement" which would have allowed me to do at least a temporary fix, but I literally cannot find "rubber cement" in the big box hardware store I usually go to. The closest thing I can find is "Goop" which promises to dry flexible and says it is good for fabric but not recommended for paper. Does anyone have any recommendations?
