For the Pahlevi Dynasty (1925-1941), you want this volume:

I'm currently waiting for Mr. Sadri to publish a new edition of the 1897-1909 issues, due out by the end of the year, at which point he says he will offer an e-book "bundle" of all four volumes. The books themselves are not inexpensive, so any savings is a good thing. I prefer digital versions anyway.
