What Kind Of Books Did Your Parents Have When You Were A Child?

What kind of books did your parents have in your house as you were growing up?
Not books for you, but books for them. . .
See, as i was growing up my parents had books on the theory of alien civilizations & extraterrestrial research, amongst other things such as psychology books & books on unexplained phenomenons.
Today I am very interested in these things, especially the alien stuff.
As my mum was growing up her mum had a lot of books about the workings of the brain & a lot of encyclopedias & today she is very stuff like that.
From this i saw a pattern.
How about you?
Do your current interests stem from the books you grew up around as a child?
