I could not possibly give up my books. I always have my nose in one...at breakfast, in traffic jams, at lunch, in the bath, the list goes on. We have a way to go to catch up on mother in law, she has over 5000 and Mike's cousin has over 10,000. But they're very academic and prob most are text books.
I am an avid recipe book collector, never do any of the recipes but they are a great source of inspiration; also, gardening, smallholding, sustainability, build your own, animal care, and of course all my piles of fiction.
I could go on all morning...looks like I have.
I'll shut up and go do something productive now...
