It is not comprehensive. It is intended to introduce the novice student of SF literature to the major themes in the genre, as well as books and authors who are representative of different eras in SF lit (including the present day). So you'll find a mix of old and new here, as well as fan favorites tucked in among more literary authors.
Back in the mists of time, I used to teach literature and American Studies at the University of California at Berkeley, so I have some experience putting together course materials for university classes very much like one. (In fact, there are a few books on here that I used to teach.) What educators aim to do in overview courses is expose students to the broadest possible set of examples of a genre, not just the "canon." It is in this spirit that I chose the books on this list.How to Use This List
The course is divided up into six sections, each with a collection of books that range from canonical classics to works off the beaten path. Ideally, you will read all the books on the list. But if you don't have the time to read them all, I suggest you sample one book of your choice from each section.
Where possible, I have linked to free versions of these books online. Where that isn't possible, I have linked to sites where you can read part of the book, and buy the book if you choose.
