I am a firm believer in re-reading. I would be. As a student and a teacher I spent a great part of my life reading a re-reading and re-reading again the same volumes, and I never tire of a good novel, how ever often I do this. As a bookseller of course I like people re-reading old favourites as it means they are often buying out of print books!
If you wonder what you would get out of re-reading then have a read of Kristen's posts on the subject and if you're interested then follow We Be Reading as she says that she will try again with the challenge in the spring when people might have more time. For further inspiration there is a good re-reading review on Shelf Love here.
My own favourite re-read is Middlemarch by George Eliot. I read it once every three years or so. It is about time I started it again. Comfort reads are often good re-reads such as old children's favourite (the Jill books, or Follyfoot, Honor Arundel's Emma books all spring to mind).
Do you have a favourite re-read?
