I find actually listing the books I read throughout a year a troublesome enterprise. So many of them end up half-finished, somewhat-skimmed, or otherwise partially absorbed that I'm generally left with a fairly small number of books read, and a somewhat overwhelming mass of books somewhat read. I am, after all, no George W. Bush. That said, I'd like to do a bit better of a job keeping track of my books. I seem to remember there's some sort of online library tracking thingie people like, but I can't recall what it is. I may be thinking of LibraryThing, but that appears to cost money, something which my books already consume too much of. Though I do love their final promotional bulletpoint (scroll down).
