How do you order the books on your shelves?
They're grouped by author, then, if part of a series, in order from first to most recent. My media tie-books are grouped together, then grouped again by the show/movie if I have more than one tie in for a particular show or movie. Also, books by an author and any pseudonyms they use are also grouped together. My book cabinet tends to follow the same set of rules for the most part.
