You'll want to read all three books mentioned, as well as "Masters of Light", "Man with a Camera", "The 5 C's of Cinematography", "Image Control", "Film Technology in Post Production", and several others, as well as the AC magazine and ICG magazine.
For a historical grounding, I'd also read "Film Style & Technology: History and Analysis" and "The History of Movie Photography".
There are also reference manuals like the ASC Manual, plus some on lighting, cameras, etc.
There is a $20 book at the ASC Bookstore site called "Selected Tables, Charts and Formulas for the Student Cinematographer from the American Cinematographer Manual" Edited by Stephen H. Burum, ASC. The title is really catchy, isn't it? Sort of a cheaper way of getting some of the info in the ASC Manual for the student.
I think for an all-around general view on the art and technology of cinematography, I'd recommend Blain Brown's "Cinematography" and Ross Lowell's "Matters of Light & Depth".
My book, the 3rd edition of "Cinematography", is more of a practical book on shooting & posting, mainly in 16mm. We didn't go very far into artistic issues or the history of the art form, nor cover a lot of big-budget equipment used mainly in 35mm productions. On the other hand, it's a cheaper book than Blain's, mainly because we weren't allowed to put color photos in it.
For good interviews with DP's talking about their art & craft, I'd recommend "Cinematography Screencraft" and "Masters of Light". There are some others worth reading too: "Hollywood Cameramen" & "The Art of the Cinematographer" (both covering classic studio cameramen), and "New Cinematographers".
I also recommend "Film Lighting" by Malkiewicz.
Better get started reading. When you're finished with all of those, I have some more to recommend...
