I recently saw a rave for LibraryThing in the Poets & Writers magazine. But this is such an old idea in Web 2.0 tagging era no? So nothing to rave about here. Besides, I saw that there is a WTF limit on the number of books you get to catalog for free: 200 (come on folks! even kid bibliophiles read that many by the time they are ten!), and then you pay. As I am too stingy (yes, I am addicted to free stuff; staying in the university for far too long does that to you), I am now considering setting up my virtual bookshelf at one of these places: Reader 2, All Consuming (I will mostly go with this one, no yucky ads so far here), or the (somewhat unstable) English version of the Chinese hit Douban. Y'all try these out too, and tell me what you think.

I also should buy one of these (still yucky-mucky) scanning pens soon, so that I can scan text that I usually underline, and upload it to my online "bookshelf".

Update: Someone who is passionate about LibraryThing gave me a gift membership, and provided a comparison of these few services. See the comments.
