Where to find oil/bomb diagrams?

I'm level 10 playing on normal. The only oils I have are necrophage, specter, draconid and the one for fiends and ladies of the wood. Is there a merchant where I need to buy them? Can't find them in any loot.

There is also...

An alchemist northeast of Oxenfurt with a fast travel point called 'the Herbalist' that sells all of the bombs and potions, not sure about oils, I think he sells those too.

Most of those however you can pick up in various different locations. I managed to find almost all of them in my play-through and I didn't buy too much from vendors(as far as I remember). I don't yet know if the pick-ups are randomly generated or whether vendors sell unique diagrams or ones you could pick up yourself, so there's that.
