Reddit mentions of The Handbook of Narcissism and Narcissistic Personality Disorder: Theoretical Approaches, Empirical Findings, and Treatments

There is not a lot of reading on it, because there hasn't been much (if any) research on these specific descriptions. This could be because of the historic difficulty we've had in adequately and accurately measuring narcissism, and with some of the flaws that the DSM has in its description of NPD.

In terms of "sub-types" of NPD, the closest things that the literature has to offer right now deals with the construct of narcissism itself, rather than the personality disorder. (Whether or not they are actually sub-types or just seemingly paradoxical traits is debatable). I suggest looking into Overt/Covert or Grandiose/Vulnerable narcissism (they are the same thing, just different titles). These seem to be somewhat similar, at least in name, to the fanatic and paranoid sub-types that you mention. I recommend research articles over books, as there is a peer review process to help ensure that quality material is published, but If interested in NPD and looking for a book, this one is written by a couple of current researchers. I haven't read the book yet, but the editors (Campbell and Miller) are respected in the field.

Good luck! I'm glad to see others interested in this area.
