Oh, this was so necessary. What’s That Book is a website “founded by former Google Answers Researcher ‘Juggler,’” at which you, dear readers, can get real people to sleuth around for the identity of that book you almost-kind-of-sort-of remember from way back. You provide all the details you can muster, and the What’s That Book people do the rest. For free.

It’s also pretty fascinating to read about what other people are looking for, and the details they remember.
