My challenge in 2014 will be to keep track of what I read, try to keep the number of "active" series down and finish the challenge I started in 2013 of reading a book published in every year since I was born. I haven't made much headway with that last challenge in 2013 and still need to read 26 books for that.
As an unofficial challenge I want to read some of the longer books that I've bought but never read.
I've set up a page on my blog where I keep track of my reading and challenges:
