My public library has changed two things recently which I have been waiting to weigh in on until I got used to both and could assess based on patterns and problems/benefits I encountered.
1) The switch to automated check out stations. When this was first done it meant longer crankier lines of patrons unable to check out their materials and figure out the system. I have to say that I love it. There is one huge glitch though. I few weeks ago, me and the hubby went to check out audio books (the main reason we use the public library) and checked out four items. When Zach went to renew the items a few weeks later they were not on his account. So I looked up the books online in the catalog and all four books said they were "claims returned". So we went in to the library to find out what was going on, and it turns out that the person in front of us never checked out of their account. So even though we scanned Zach's library card, the system still registered all 4 of our books on that patrons account, who then called the library wondering why the heck 4 audio books were on his account. This scenario made me a little paranoid and now I keep checking to make sure my account is cleared every time I go to the library.
What I also don't like about this is the human factor. I think it is one more way to give less service to patrons. If patrons want to self check out, then fine, but the option to have a circ staff there should also be available- after all, a lot of the patrons I get at the circ desk are happy to talk, laugh and share information about the resources they are checking out or just about their day. The more positive human interactions we have in our spaces the better.
2) The switch to making everything you check out due on the same check out date (with a few exceptions like the 7 day new fiction books). This means the books, cds and movies are all due at the same time: 3 weeks away. I found this very surprising and was not pleased by the thought of people having movies for three weeks, because I thought it would dwindle down the constantly small amount of available movies. However, I have found that I love this new switch to having the same due dates. It makes a lot more sense in conjunction with the self check out machines; you just have to get everything listed on your account!
