Category talk:Music publications
I propose that this page be reorganized, into about multiple subcategories. I'd reserve this category "Music Publications" for books about choral music, and music dictionaries.
Among the new categories I suggest are "Choral collections", page cataloguing collections of scores books and collections. I also propose as a new category, "Music Education Publications" for pedagogical materials. It might be worth considering another page, too: "Music Publishers" a listing of publishers of choral music, which might provide information about when a particular publisher was established, and what happened to it.
On further reflection, I believe I'd define a new category could be created for books about choral music, and music dictionaries, and use the Music Publications page (which needs to be added to the navigation contents bar) as a Meta page, listing all of the subcategories.
