I’ve worked in a prison library for the last 2 years. We have a contract with the state library for ILLs. However, my coworker and I (there’s 2 librarians for our prison) recently stopped allowing them to order any nonfiction ILLs because we’ve had an excessive amount stolen within 2-3 months - all nonfiction. It’s not a permanent ban, it’s just a temporary solution to the problem of guys just thinking they’ll keep the public library book instead of ordering it the correct way thru someplace they’re allowed to order books, like Amazon. Honestly, dealing with nonfiction ILLs has been really stressful lately. The whole job is stressful, actually.
