I like the having two classics months because it is not really a genre in the way say Sci-Fi or Mystery is. It represents books that have stood the test of time and are still read and discussed. The test of time (i.e. not recent) being one of the defining attributes of a classic. The free part is just an added benefit. I would strongly object to having a month devoted to any ebook that is free, including selections such as Free First Book by Who The Hell? offered as a promotion.

I actually would be warm to the idea of a prize winner month. It would have to be a major prize though, say as others have suggested Nobel or Pulitzer. Not best Science Fiction of the year, or anything like that. One thing to keep in mind though is that the Nobel prize is an award to an author while the Pulitzer is an award to a book. However, I am with Sun Surfer in that if we are going to add a prize winner month I would prefer making room for it by combining two very similar genres that each now have a month into one month for the two.
