To get your recipes, you need to join another society. It's an "advanced" society. These societies are found (At least mine) in the town that has your inn/apartment. And the wholesaler in this advanced society has for instance, "outfitter Essentials Volume 11", and it also has recipes for the 20+, for instance, "Armorer essentials volume 20". You do not have to leave your current society to join the advanced one. Good luck and have fun.
