Update -I decided I didn't like the Shelfari Widget, and have removed it. I have replaced it with an Amazon widget recommending books I like.
Found this widget on someone's blog and have decided to try it myself - I think you just add the books you are reading/have read, and you can also write reviews etc'. Since I love and use books a lot, I think this might be fun.
I don't often read fiction, but I'm reading a lot of jewellery books at the moment!
You can find it on the bottom left hand side of my blog. Not that much there yet, but I will be adding to it!
