I hoard books; real books and audiobooks. As middle age is well and truly here now, I'm trying to read through my stashes and limit newer books bought to those I simply must have and read.
My main challenge is to read all of the 1300 plus books from the 1001 books you should read before you die lists. Plus I love horror and historical fiction.
Audiobooks are my preferred medium, I am seriously addicted to them. I can't get used to my kindle though and by far prefer real books.
