You know what I’d like? An easy way to keep track of the topics I’m
reading about, and a way to visualize that over time. LibraryThing or
some other Amazon-hooked services wouldn’t be a bad way to get the
data in. Then it’s just a matter of looking up the category. I can
also keep track of links between books and people, and also links
between books and other books.

First things first: find an unobtrusive way to get the data into the
system. I’ll need it datestamped and indexed by ISBN. Ideally, I’d
have this just automatically hooked into my library checkout page, but
I haven’t checked if they’ve embedded ISBNs into the checkout list. If
not, I can enter them in manually, although numbers are a bit of a
pain to type accurately.

Hmmm…
