Interesting discussion on the Talk Pages. Here is their criteria:
From the article: What counts as a novel is another variable. For the purposes of the list, a “novel” is defined as a single work in print or electronic form that has been published through a mainstream publisher and that has acquired publishing rights from authors. A “single work” includes works thought of as one novel by the author but published in multiple volumes for reasons of convenience.
Excluded are self-published, printed-on-demand, and vanity works, unpublished novels like Henry Darger’s, novel sequences like the Chronicles of Barsetshire, novel cycles such as those set in the James Bond universe, and record-grabbing stunts written solely for the title of the longest work.
In addition, there is no bottom limit for page count, but anything over 1,300 pages is bound to get on the list and many above 1,100 pages will make it on. Instead, the criteria is word count, and a novel needs a word count of over 500,000 words to get on the list. Which rules out a lot of doorstops like Pynchon’s novels.
Problem here is that they have allowed many novel sequences and novel cycles on their list while saying novel sequences are banned. Well, which is it?
For instance, the list includes the following novel sequences of novel cycles:
James Fenimore Cooper “Leatherstocking Tales.”Probably the first novel sequence from the 1820’s.
Thomas Mann “Joseph and His Brothers.”
Anthony Powell “A Dance to the Music of Time.” His masterpiece.
Henry Williamson “Chronicles of Ancient Sunlight.”
Marcel Proust, “À la Recherche du Temps Perdu or Remembrance of Things Past.”A roman-fleueve. his masterpiece, in fact, he wrote little else.
Jules Romains, “Les Hommes de Vonne Volonté or Mean of Good Humor.” A roman-fleueve. His masterpiece.
Roland Romain, “Jean-Chistophe”. A roman-fleuve. His masterpiece.
All of these are listed on the Wikipedia page about novel sequences, novel cycles, and roman-fleuves. Roman-fleuve was coined by Romains about his novel, “Men of Good Will.” It means “river-novel.” Proust’s work is considered a classic example of a roman-fleuve.
I think they need to make up their minds. Either allow all novel sequences or ban all novel sequences. Right now they are allowing novel sequences, except in cases where you are disallowing them! You can’t do that.
So I set about thinking up all of the novel sequences, novel cycles, roman-fleueve, and long standalone novels I could think of and this is what I came up with. Of course I had to look up how many pages (to see if they should be included, or if so, the number of pages) or in a few cases how many words they had.
If they are going to allow the seven novel sequences above, the works below ought to be considered as additions to the list if the word count is high enough.
List follows. Let me know if you can think of any more.
