This book is a classic on Getting Things Done.
It is the first majorly-popular business book that outlined an effective strategy for dealing with paper and prioritization of said information overload. The processes outlined are, as near as I can tell, guaranteed to work if actually done. Amusingly enough, however, nearly all the details are for a world that doesn't really exist any more. The copy I read was from the nineties, before the Intarwebs became a household phenomenon. As such, there are a lot of paper handling tasks, a lot of folders, the use of a label maker, and many techniques that aren't specifically applicable any more.
Also, the focus of the book is more for managers, and less for, say, the workers, the coders, the engineers. Oh, many of the techniques do apply, but they aren't all relevant.
Given this book is a classic, and given that I did get good use, ideas, and processes from reading it, I do recommend it.
Just not the paper parts.
