Do you prefer reading current books? Or older ones? Or outright old ones? (As in, yes, there’s a difference between a book from 10 years ago and, say, Charles Dickens or Plato.)
It doesn’t matter to me when a book was published. A good story is a good story.
I try to read a good blend of both old and new, though a lot of what I read is newer. This is because of reviews I find, recommendations from friends and the shiny covers at the bookstore and library.
One thing I hope the revolution toward e-books will do is allow older books to remain in print and circulation longer. After all, if they only have to exist as electronic files on a server, then it shouldn’t cost as much or take up as much shelf space to keep them around.
