I've always done this, even at the expence of missing out on new exciting experiences. There are some books that never get to sit in the shelves. The worn dog eard pages are a testiment of love i guess, even if it does annoy me sometimes that i'd rather read an old favorite than find something new.
I'm currently re-reading Rendezvous with Rama by Arthur C Clarke... Well i say re-reading but I've actually even picked up the audiobook version so i can visit my favorites while at work, at the gym or out for a walk. But hey! At least my worn books get a bit of well deserved rest that way.
The dune books, the guards series of books by terry pratchett, the somnambulist...
