Wouldn't it be nice to have all children's literature categorized by theme? So if you need to talk about something with your class such as relationships, behavior, etc. you can look for literature that has that theme as an introduction to the topic. There actually are several database programs available that can do this. To find a list of these, go to www.softseek.com
and search for "book organizer." It will describe them, and usually has a demo, and then you just download them. Most of them are freeware or shareware. For the shareware, you can usually use it for a month or so and then have to pay a small fee if you want to keep it.
