hi; there're a couple of publishing categories definitely needed, as no combination of any two or three of the others will serve; and these will combine with a number of the existing categories to cover quite a range not currently catered for:
i. which-way multi-pathed adventures
- will combine with most forms of category fiction, and though i've not actually met any which way/choose your own way westerns, i believe these exist, too.
ii. erotica
- will combine with fiction of most kinds, also poetry, art, sculpture, photography. . .
iii. role-playing games rulebooks, sourcebooks & adventures
- there's an enormous spectrum of role-playing games from dungeons & dragons and tunnels & trolls, through traveller, call of cthulhu, middle-earth rpg, rifts, various superhero settings, cartoon worlds, wars historical, future and other, etc. - all of which are printed, bound (in various ways, including hardcovers & paperbacks), given cat#s and isbns - they're books, but we don't have any category or category mix as fits them.
iv. westerns.
- nowhere near as widespread as they once were, there're nevertheless thousands of these languishing(!) unrecognised by "bookcat". . .
We're trying to limit the "genre" options to a small number of broad genres. More specific genres can be done by using the Class Number system on Book World (similar to Dewey Decimal).
yes, that's why i took the time to think through and limit the number of suggested categories - there's elsewise too many possibilities, including ones like "film novelization", "tv novelization" and even "play/drama novelization", and diito "spin-off"s: but many of these are really sub-divisions of existing categories, and can perfectly adequately be indicated by use of series' tags where they proliferate, such as doctor who, star trek & similar spin-off original novels.
i believe three of the four i've suggested are not sub-divisions of existing bookcat "genres", however, and all four, including "westerns", to be ones that would be both broad enough to be useful and define & categorise areas of interest, or mark off areas that do not interest, bookcat users and browsers.
The way we are doing book genres is to imagine it like sections in a book shop. A small number of very broad categories to browse by. Then the Class Number (Dewey Decimal) system is there for people who prefer to browse as if in a library.
