I'm not going for a specific goal in 2013. I felt I was favouring short books too much this year, to make sure I got my 50. My main aim is for my TBR to go down instead of up.
As a subsidiary goal, I think I'm going to try to finish off the list of Hugo winners. I originally decided to read the whole lot 3 or 4 years ago, at which time I'd already read half of them. I now have just 9 to go, and when I've finished my current book, none of them will be "blocked", so I think I ought to be able to fit them all in, along with 2013’s winner.
I'm also planning to start on my Detectives A-Z list (see other thread), which is so far mostly undecided, but I think I'll just try to read, say, 8 of them, rather than all 26.
