one of my regrets is not being disciplined about logging my book reading. It would be *very* useful to have a long list going back 20 years, of all the books I've read
I've had half-assed ideas about reconstructing it from amazon purchase records and limited library checkout info and just going through my paper-book collection but it would be a serious schlep and incomplete
A very quick way to do this (going backwards, going forwards) if you don't have the discipline of a Cosma, is to just use http://GoodReads.com
Even for someone as lazy as me it's fairly easy to just add a title each time you are done, with optional star rating and review.
