Reading paths
I like the idea of the reading path or cluster. In addition to canons or course syllabi, we could make lists of books that are good to read together in order to understand something central to feministsf. But this is kind of a different idea than a reading list based on a theme. Each path would be like a guided tour... "read this, then this, then this, then think about this other book."
Or, for some books, "in order to understand this book, you probably should have read the following..." For example, to "get" Vonda McIntye's "Little Faces" or Lois McMaster Bujold's later books in the Vorkosigan series, I think you need a background in space opera and romance novels. This will help us to define a genre: the genre isn't a canonical list of the best examples of some idea - it's a sort of cloud or field in which we draw lines of connection.
