Where to Find the Rarer Books?

[NatNit]

So, I'm looking for a few items (and I have been for quite a while), but I'm not quite sure where to look. I'm so desperate for them, I'm willing to do "runs" to obtain them.

Oh, and no shopping: this is for my lvl 27 LoL mage:

• book of fireball<>
  
• book of chain lightning<>
  
• book of teleport<>
  
• dreamflange<>
  
• a decent shield<>

  I'm already rocking a Royal Circlet and Naj's Light Plate, so we're okay in that regard.
  
  I don't think the books can drop in the catacombs bookshelves, so I think I'll have to kill monsters to get them to drop. :/
  
  Thanks,
