17. LibraryElf

LibraryElf is a service that allows you to keep track of your library materials, mostly to prevent overdues.  While this seems like a great idea, I don't think it would help our patrons all that much.  First, we aren't even a supported Library, so you can't sign up.  Second, although you can get alerts for a single card for free, if you want to be able to track the items on multiple cards (like for your kids, etc.) or receive text message alerts, it costs $20 per year.  Financially, unless you're incurring lots and lots of fines, this doesn't really make a whole lot of sense.  Especially when you consider that you can access your account on our site for free.
