I thought I'd give kindle a try but I really dislike the format. I love books, the way they feel in my hands, even the way they smell.
We just had some bookshelves installed, flanking the fireplace, in a recent remodel. There are literally zero rooms in our house, including bathrooms, attic, basement, 4 bedrooms, kitchen, pantry, family room and living room that do not have books in them. Shelves and shelves and boxes and stacks and some, just randomly placed.
Hubby is still in academics so the house is littered with books and publications related to his field. I still have a bunch of biology and biology related books, some texts (I really do need to donate those) as well as more popular press books. We both have our own favorite sci fi and he's into mysteries much more than I am but I will take a moment to plug Tana French's Dublin Murder mystery series. You may have caught the short series that covered 2 of the books. I liked the miniseries well enough but the books are much better. I also like poetry, Shakespeare, Trollope, Austen, the Brontes, Atwood, Tepper, Ephron, TH White, and dozens of others. He collected chess books for a while and other sports related books. I have some gardening stuff. Cookbooks, of course. Lots of popular fiction and non-fiction...
I will be doing more culling this winter, once the cold weather sets in.
One of the nicest things any of my kids has said to me is that one of his main memories of his childhood is that the house was always filled with books and music and that he was profoundly grateful for being raised with both.
