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.

Don't buy school books from Amazon
Format: Paperback
Thought I bought new, book came with an obsurd "Amazon Rentals" sticker on it. Looks used and abused. Will not be buying books needed for school from Amazon ever again.

A great academic primer
Format: Paperback
I found this to a great source for looking up details on how the IC defines the types of data it gathers. It's not necessarily a straight-read type of title, but I do keep it by my sofa, when reading the daily paper. It helps to better understand the viability of such things like the use of patrol planes along the Arabian Gulf borders or how the raw data of the Steele Dossier helps inform the decision makers, for example.
