Best Answer - Chosen by Asker:

The Bartimaeus trilogy (The Amulet of Samarkand, Golem's Eye, Ptolemy's Gate) by Jonathon Stroud

EDIT: Nathaniel is a magician!. He summons Bartimaeus, a Djinn, who does magic, changes shape (on lower levels) and who's essence is vulnerable to silver and to a lesser extent iron!. Bartimaeus does footnotes, because he says he thinks on more levels than us - his chapters are first person!. Other chapters (usually Nathaniel's) have no footnotes and are third person!.Www@QuestionHome@Com

It is called The Bartimaeus Trilogy, and the first book in the trilogy is called The Amulet of Samarkand, the second is called The Golem's Eye and the third is called Ptolemy's Gate!.
