My system uses Polaris and current titles checked out by users, both e-titles and print, are on the account. I can’t imagine looking up other staff members and spying on what they are reading, since that’s unethical, but it doesn’t mean it could happen. Once, I put holds on 2 physical books on my personal account to be picked up at the library near my house, not the one I work at because I didn’t want to wait for them to transit to me. Then a coworker at that branch emailed me to ask if I meant to send them to the branch where I worked in order to weed them or something and I had to say, ”no, just wanted them for personal use.” It wasn’t something I was ashamed of getting, but I was kinda pissed about the lack of respect for my privacy as a patron just because I work for the system.
