The recipe catalog covers every learnable crafting recipe Blizzard ships in the live game data. The subclass column tells you which profession the recipe belongs to — leatherworking and jewelcrafting carry the deepest recipe pools in the catalog, with blacksmithing and tailoring close behind. Each entry shows the recipe's display name, item level, required level, and quality tier.
Recipe pricing has a different shape than commodity pricing. A common recipe drops to a low floor quickly because every player who finishes the relevant content learns it. A rare recipe — one with a low drop rate from a single boss, or a world drop — can hold a high price indefinitely because supply trickles in slowly. The classic editions sharpen the split with limited-supply vendor recipes that restock on slow timers, so the auction price there is largely the price of not waiting at the vendor. The history chart on each recipe's page separates the shapes at a glance: a flat line near the floor means the recipe is common, while a noisy line above the floor means listings are scarce and contested.
The Book subclass sits apart from the profession lists: tomes and manuals that teach abilities or profession specializations rather than single crafts. Many are world drops with tiny supply, which gives them some of the most erratic charts in the whole catalog — long flat stretches with no listings at all, then a single posted copy that sets the price on its own.
Recipes are also where cross-edition comparison earns its keep, because the same pattern can be a contested rarity in one edition and a vendor afterthought in another. The edition selector on each recipe's price-history page makes that split visible. To hunt one recipe by name, the search box on the item database home page narrows quickly; the "Browse subcategories" links below step into the per-profession lists so you can scan one profession's pool end to end.
