Nonfiction titles to accompany our SF-F titles

The Wheel of Time Companion book will be coming out later this year, which made me think of other nonfiction books that can make good companion reading to some of our SF-F books.   For example, we have "An unofficial companion to the novel of Terry Pratchett" edited by Andrew Butler (823.914 UNO), "In other worlds: SF and the human imagination," by Margaret Atwood (809.38762 ATW), and more.   So, if you're looking for some reading to accompany some of your fiction books, take a look at our nonfiction area!   And you may always ask one of our friendly staff for suggestions or assistance.
