I don't really have a TBR. I don't buy fiction unless its to collect them (as I'm doing with the Rebus series). I have a list of books I'd like to read, but as I'm restricted to what my local library holds I know there's some on there I won't get to read. I usually have about 10 fiction books out of the library at a time, or I don't get them read before they're due. I read those before anything else usually, so I guess they're the closest I've got to a TBR. I do have a lot of non fiction books that I own, but some of those I won't get round to reading, and others are more reference type ones. I'm slowly making my way through the ones I want to read, but it doesn't bother me if I don't get to them all.
