Small print
Format: Paperback
I like the content, it's really interesting. But the print is so tiny, what makes reading kinda annoying.

A Tradecraft Primer
The Tradecraft Primer is very useful for anyone going into the intelligence field. It explains many of the different techniques used in the intelligence community to get analysts to expand their thinking. However, you can find the contents of this book online (as I found out after I already paid for the book), so you don't need to buy it unless you want to have a hard copy.
