Books on IT (not Project) Management

bangpath asks: "I realize that many of my peers aspire to become managers in their field/respective subfields, but upon visiting Amazon and Barnes & Noble, I noticed a significant lacking in books about IT management. That is, most books that came up under this search were IT project management or IT systems management. Surely, these are important areas that an IT manager deals with frequently, but what about dealing with the people, policy, and responsibilities of IT? One would think that IT workers aren't the same as HR people, or Accountants, or the other types of people you'd find in a typical office. Can anyone recommend any books specifically about managing IT Professionals?"
