I have a pretty old book that has a hard cardboard sleeve that’s really frayed at the corners, so that the bottom part of it is coming off a bit. What kind of glue would you use? I want to keep it from fraying again or damaging/having weird effects on the material over time.
Without being able to see it (and I’m no expert anyway), it’s hard to recommend anything specific, but whatever you end up using (glue, tape, etc.), make sure it’s labeled “archival”. That’ll ensure it won’t discolor or whatever down the line.
Thanks!
