The types of books they shelve tells me a lot about that person, their education level, their interests, even their politics to some extent.
I think having books around the house does foster lifetime reading habits in children and greatly improves their overall level of education.
It's also important to let children gravitate to what they enjoy reading rather than force certain reading on them. Let them read whatever they want. The more they read, the more they will seek out.
Our home was filled with books. My children grew up surrounded by books in every subject, and they loved reading. They truly appreciated receiving books as gifts, too.
After reading all of the people on this thread talking about their childhood book reading I guess I need to throw my two cents in.
Every single thing Asimov wrote.
Every single thing Heinlein wrote.
Dune (the entire thing)
All the Ace double science fiction books.
And all of Edgar Rice Burroughs.
Anything the school library didn’t nail down before I got there in the morning.
