The Domesticated Primate

It turns out that Douglas County DOES allow search by ISBN, it's just very much hidden in some seemingly-unrelated menu: "Alpha browse (starts with)". I had even called them about ISBN search, and the person I talked to didn't think ISBN search existed anywhere on the site, either, so it's well hidden even from the folks who work at the library. :)

I'm glad I was able to find this, since Douglas county seems to have nice facilities, at least at the Lone Tree branch. Not too sure how good their catalog is, but I have found a few things there that Denver doesn't have.

Anyway, you can check out the Douglas-Amazon script over at userscripts.org.
