From Cynthia Grabo - godmother of warning - comes Anticipating Surprise: Analysis for Strategic Warning. Basically the declassified text of the definitive guide to strategic warning that has been taught to generations of watch standers. Highly useful today as both a study in how it should be done, and a resource for dealing with the issues that impede our ability to survive in an age of perpetual warning.

Best Truth: Intelligence in the Information Age has got to be one of my favorite books on intelligence and reform. Written before it was all the rage, it identified problems with process, technology and other factors that would be highlighted by the after action reports of future intelligence failures.

A primer on 'roids, IC maven Mark Lowenthal's Intelligence: From Secrets to Policy has been used as a text for both beginning and advanced instruction in the community. In many ways it is a blueprint for how the nature of work community-wide shifted over the past few years - reflecting a CIA-esque approach - a shift that the author had just a skosh of a role in (insert wry look here). An excellent companion to Silent Warfare.

An excellent primer, Silent Warfare: Understanding the World of Intelligencenis used as a textbook by a number of intelligence instructors. A good place to start if you are new to the field or an aspiring practitioner.
