Which monsters do i have to fight them?

i've already got the ones from bat and spider..

Bats, Spiders, Ice Vivis, Zombies, Tomb foxes, Grave wolves.

Not sure about Ice Vivis but I think you can get some books from two different mobs. But I'm pretty sure I got my last few ones from the last three mobs on the list there.

Just keep fighting stuff in MT til you get them all D:

Yeah, agree with Yosei. I think the higher number book requires higher level mobs. So once you get the low level ones, get the high levelled mobs.

King Staves also drop Page 5.
