"Jail Library - These are things I find abandoned in books or stuffed on the book cart at the jail where I volunteer.
I've thought long and hard about privacy, and asked jail staff, a law librarian, and others if sharing these was OK. The concensus was yes, as long as no identities are revealed.
We don't keep track of who borrows what books, so finding the creators of these items would be as hard (if not harder) than finding the creator of a doodle on a napkin in a public trash can. (That said, if a former patron recognized something they did, I'd take down the post and give back the original.)"
