Useful source books for crafting rules?

Games Discussion Ars Magica

I'm hunting for a breakdown on crafting rules. How to craft basic items, item on mass, and then expanded to include the guidelines for using magic to accelerate these. Digging through the forums it seems that City and Guild has the expanded rules for crafting by mundanes ([url]https://forum.atlas-games.com/t/c-g-question-about-crafting-and-time-amount/4262/1]).

So I'm hunting for a copy of city and guild.

Which other source books are useful for crafting?

Covenants has some rules on that too.
How to earn money by crafting things, how to save money with specialists etc.
Some spells to improve crafting.

Ancient magic has some rules about Automats and Magical Architecture but that's not really crafting. Nonetheless cool stuff.
