Publish, er

For something so close to bloggers, poets, songsters, scribes of every description - we appear to be at an impasse when it comes to sorting publishing of books by genre. Wikipedia mixes in non-fiction (in an article that baldly states books can only be fiction or non-fiction) categories. Goodreads covers more but is 'chancellorsville-campaign' worthy of being a genre and of noting there are 20 books dealing with the subject?

For our list I intend to borrow from the Daily Writing Tips site as their article focuses on fiction.

• adventure
• airport novel
• bildungsroman
• black comedy
• comedy
• comedy-drama
• comedy of errors
• comedy of manners
• crime
• detective fiction
• epic
• epistolary
• fan fiction
• fantasy
• flash fiction
• genre fiction
• Gothic
• historical fiction
• horror
• melodrama
• mystery
• parody
• pastiche
• Picaresque
• roman a clef
• romance
• romantic comedy
• romp
• satire
• science fiction
• screwball comedy
• slash fiction
• slasher
• swashbuckler
• thriller
• tragedy
• tragicomedy
• travelogue
• war
• western 

The genres in italics are for fiction that has probably never been presented on the page, only on screen. And computer screen at that. This explains the short forms like flash fiction and its close cousins nano-fiction and twitter fiction
