How many, and what kind of, books, did your family have when you were a kid? And how did it affect what books you read now?
My father had woodworking books and Popular Mechanics magazines. My mother, romance novels and diet books. High culture consisted of the Bible and the Encyclopedia Americana.
This did affect my choice of books, in a strange way. Due to the dearth of reading matter at home, I had to get books from the library, and would read anything I couldn't get at home. Since I read slowly, and checked out too many books at a time, I sometimes couldn't finish them all before they were due. I so longed for the ability to own a book, instead of borrowing it, so I could read it at leisure.
Now I have a room in my house set aside as my library. It has literature (fine and popular), history, religion, social science, current events, mathematics, science and techology (and not just popular expositions), and of course language instruction. But no treatises on woodworking or cheap romances. And I'm already out of shelf space.
