Great structure
Format: Paperback
I had to get the book for class, so did not exactly get it because I “wanted to.” It was a good read though. I liked the structure of each section. Everything simple enough to understand while also diving a bit deeper.

A must have for every intelligence professional - collector or analyst!
Format: Paperback
An excellent resource for any intelligence collector or analyst. The chapters are written by world-class experts in each discipline with an excellent final chapter on collection management written by Drs. Lowenthal and Clark. Each chapter defines the elements of the particular intelligence discipline, its history and producers, as well as how the INT is managed and explores likely future trends. An extensively researched and documented text that is nonetheless an approachable resource that would make an excellent addition to any intelligence related syllabus.

Good Review of the Intel Disciplines
Format: Kindle
I rented this book as required for an intelligence collections course I as taking. It is a good rundown on the different INT disciplines and the bureaucratic organizations managing the different INT categories. This book does not really touch on the various collection programs used to manage collections, or what the nomenclature of those requirements are, so reading this book will not teach you about intelligence collection management beyond gaining a foundational understanding of what the various INTs are used for.
