Hmm, looking at my bookshelves, I like fiction & non, poetry, history, philosophy, classics & contemporary, folklore & myths -if it's iconic, I want to read it. Some books define cultures and help readers understand their own values. Those interest me. I'm even trying (unsuccessfully to date) to read Richard Feynman's "Six Not-So-Easy Pieces." Wish me luck 'cause math's not my mother tongue.
