The regular ones are sold in your Workshop Society, the Advanced are mob drops so I guess they will also crop up on the broker.
Just to expand a little, when you first sign up for a society, that will be the begining crafters (1 to 10)society, once you reach level 10, you should now be able to access a second society in your starting village, that second society will be the advanced society set to your particlar tradeskill (Scholar etc) That advanced society will be where you locate the more advanced manuals 10 and up)
