About a year ago, I suddenly lost interest in my spreadsheet of books. I got behind on updating it, and I never got back to it. I am still reading, though!
Mostly, I am re-reading lately. I have re-read most of my Sheri S. Tepper books, which I always enjoy. I got a set of the Galactic Mileau series by Julian May, and that was a lot of fun to revisit. Now I need to get the Intervention and Pliocene Exile books. It has probably been 15 years since I read those books, long enough that I can re-read and be surprised by a few things. And, right now I am reading the Harry Potter books, 4 through 7. We seem to have lost the first 3, or I would be reading them, too.
I am re-reading for a couple of different reasons. First, obviously, is the economic reason--it doesn't cost anything to read books that I already own! My children have reached ages where they seem to be outgoing all of their clothes all the time, no doubt because they eat all. the. time. So, it is nice to have a large library of books that I can go to for entertainment at no extra expense.
But, I also find it a bit comforting to re-read. I love picking up a book that I already know I will like. A lot of the books I re-read, I may not remember the details before I read them, but I remember what it was like to read them. I can revisit what it was like when the ideas were new, or I can remember things that were happening in my life when I read the books the first time around. This can lead to expense, though--sometimes I have to go out and buy a book that I remember but can no longer lay my hands upon. But I can usually find something on my shelves that meets my needs, which makes me feel good about keeping all these books. Yes, there was a point to keeping them!
