The Monster At the End of this Site
Not being a librarian in a system smaller than, say, the population of the state of Delaware, I don't have to deal with a lot of issues facing school teachers and librarians nationwide. For example, I never have to worry about starting a new catalog from scratch in a school library or classroom. Not an issue! If it were, however, I guess I'd be pretty durn excited about this Delicious Monster thingy. According to Esme Codell (who should know) the site contains, "shareware that allows you to automate your personal collection of books! That means, teachers, you can scan in your classroom collection, beep-beep-beep, and look things up and check things out, just like a real library, only interfacing with snazzy Mac graphics!".
Huh. Whodathunkit? If you want to go even more low tech, however, stick with good old Library Thing. To each his own.
