Am I on track with my targets?

Well, I've just counted up the books I've read and I've completed 40. I started reading on the 10th November so (going by weeks on my calendar) on Friday 21st November I should complete book number 42. As this is Wednesday it looks to me as if I am 1 book ahead. I could give myself a night off! On the other hand I have already selected a book for tonight, a play of about 100 pages. It looks as though I could read that AND have time to watch Billy Bob Thornton in Bad Santa ...

There must be an easier way to count up the books I've read and still have to read. Perhaps there is some sort of Gadget for Blogger. In the meantime I'll continue doing it the hard way!
