Removing labels from library discards
Does anyone know how to do this safely? I posted this question on the childhood favorite books thread, but I suspect it will get lost there.
I often purchase used books, and sometimes those are library discards. I know I must learn to live with the old card envelopes that may have been glued inside if they came from the card era. I do wish I could remove those sticky labels though. On some old clothbound books they are clued directly to the spine; on books with jackets they are attached there. In a public library such labels are a necessary evil, but if there is a safe way to remove them from books I own, I would dearly love to do so.
I suspect I am not the only book collector among our members, and I know I am not the only former or current library staff member here. I hope someone can help me with this question.
Thanks for any help.
