We were very much a reading family, but we were a borrow-a-book-from-the-library family more than a bookshelves-full-of-books family. My parents valued books, but they grew up in the Depression, aware of the quicksilver nature of money, and they learned the hard way that you shouldn't buy what you could borrow. Because of that frugality, or perhaps independent of it, they also believed that you read a book for the experience of reading it.
