on mission 4 halescourge we got all 3 tomes and both grimoires as well on missions athel yenlui, the screaming bell, fort brachsenbrucke, into the nest, against the grain, festering ground and the war camp. so some are in act 1 most in act 2 and most in act 3 of the base game campaign adventure. you can also verify this via the end of stream/video results as well.
