Untangling the Web: The NSA Guide to Internet Research

 

In 2007, Robyn Winder and Charlie Speight wrote "Untangling the Web: An Introduction to Internet Research" for the National Security Agency (NSA).

"Untangling the Web" is the National Security Agency's guide to finding information on the internet. From the basic to the advanced, this 650-page book offers a fascinating look at tricks the "real spies" use to uncover hidden (and not-so-hidden) information on-line.

On April 19, 2013, the NSA approved this guide for public release. Although the book is now somewhat dated, it still offers may useful tips for on-line research. You can download a PDF copy of "Untangling The Web" from 'The Government Attic' or directly from NSA.Gov.
