Sometimes I use this blog primarily as a log, as an aide-memoire

Last year Crooked Timber wrote about a bar code system for cataloging your own books.  Some people asked "WHY!!???" I simply take note of Delicious Library for possible future reference.

Also take note of Shelfari, LibraryThing, and Your Media Library for all of your book cataloging needs. Amazon's Media Library is the most similiar to Delicious Library as it'll let you catalog anything, but since LibraryThing and Shelfari are "web 2.0" and focused only on books they have pretty solid communities.
