When our parents call with some new medical condition they've developed, our first stop is to find out more at the library. As homeschoolers, the library is the mainstay of our curriculum, and every evening before bed, we read aloud from one book or another, most of them picked out from the excellent children's collection. And of course it's not just books anymore either. CD-ROMs are a big favorite at our house now. No one believes that's actually the title.

In the old days we had to sign cards to check books out and those cards each had a pocket. I don't know if you've ever looked at those card pockets, but you should. I like the sounds of that. And they're good at it. I know lots of librarians and let me tell you, there's quality here.
