librarything.com is a wonderful service for those who would manage their own libraries, or poke and pry into the bibliophilia of others, or explore book haiku. I’ve used it to explore my own book addiction, but I’ve just scratched the surface of its powers.
A click on the mugshot of Cappy should give a LIFO view of my holdings:
and/or explore my library tag cloud, which includes all items in the home library by their (sometimes lame) assigned categories (lots more could be done here… for instance, here’s a tag cloud for others’ tagging of the same books, a tad less idiosyncratic perhaps. And here’s my author cloud, which conveys some of my obsessions pretty clearly.)
