I’m sure tons of people have been posting about this, but I just think this is too cool. I’m also currently in class, but obviously I have screwy priorities, and I just want to post this before I forget. Superpatron led me to this post from this guy. Virtual catalog cards? That we can write on? Every library that has, ahem, disposed of their card catalogs should jump on this! Also, I haven’t been able to explore Ann Arbor District Library’s site, but I’ve heard good things.
