I love the idea of LibraryThing, and I like its features better than the similar tools I’ve looked at (like Shelfari and Goodreads). I created my LibraryThing account a few years ago, and set about cataloging my entire personal library. But I ran out of steam and I haven’t been able to get back to it. For a while I was cataloging all the books I borrowed from the library, so I could have a record of what I’d read, what I wanted to purchase someday, etc. But after a while it just seemed so time consuming – probably in part because I was way more meticulous about cataloging the right edition and tagging consistently than most non-librarians would be. I do like that LibraryThing tags and similar books are now included in the C/W MARS libraries catalog.
