Cryptocrystalline Shrikes

So I'm looking at villager trading in Minecraft while decompressing from a Thing earlier.

• Fletchers buy string and sell arrows and bows. They also help you grind gravel into flint, but that's something they need anyway.
• Shepherds buy wool and sell shears… ? And then they sell colored wool.
• Farmers… buy crops… and then sell you bread and pies and cookies and cakes. Isn't that… a baker?
• Librarians buy paper and books, that sounds good. They sell books and even whole bookshelves, okay, that's a remainder sale, isn't it? I like that.
• Priests buy rotten flesh… what are they going to do with it? I guess maybe that's a funerary practice, or studying zombies to cure them or something. They buy gold, okay, that's reasonable, they're going to use it to make religious decorations. Sell rarer materials… not sure about that.
• Smiths buy coal, iron, and diamonds, and sell armor, tools, and weapons made from it, that's good.
• Butchers… buy raw meat and coal… and sell cooked meat? Isn't that more like a barbecue shop?

Some of these careers seem misnamed. c..c
