Does your house have a communal bookshelf? If not, is your bookshelf centrally located so everyone has access to it?
Our house has a communal bookshelf, but none of my books are in it anymore, since I have my own shelf in my room. When I was little, my books were in the communal bookshelf. But now that shelf is mostly home to my parents' stuff.
The bookshelves in my room (I have a proper bookshelf, plus shelves in my closet that are sagging under the weight of many volumes) are off-limits to anyone else. I'm persnickety about my books. I'm not a lender.
