Murga is located at approximately 1128, -140, which is the farthest east building by itself when you are by the Plane of Knowledge book portal. By default, she glowers at me dubiously, I am an Erudite, and won't sell to me. I tried Collaboration, faction adjustment spell, but it wouldn't take hold. I then went through all my Player and Other illusions and she looked at them all as dubious except for the Ogre illusion which she then viewed me as warmly and would sell to me. Not having a sneak and/or FD class, I am unsure whether you can access her items that way.
The items she has for sale are as follows:
