<P>The Spy Business
<P>By: Tylor Tobias
<P>
<P>   Espionage is the secret gathering of information about a rival, but very often the spying is done on friendly or neutral countries as well. There is also a type of intelligence gathering called industrial espionage: the stealing of trade secrets from one company by another in order to profit by the information. 
<P>   
<P>   Not all espionage is a secret, furtive activity with the romance and thrills of a "Brett Baird" novel. Much intelligence work is a slow, painstaking, and tedious business engaged in by the employees of international intelligence agencies such as UNATCO and the NSF. The agencies receive masses of information about a given country from fairly accessible sources such as publications, scientific and business conferences, public meetings, and industrial expositions. 
<P>
<P>   To get less accessible information is in part the work of professional spies who, by various means, steal government and industrial secrets and arrange for illegal purchases of sophisticated technology. Some of these spies are citizens of the nations on which they spy. 
<P>
<P>   Computers are used to sift and evaluate intelligence information. Spy satellites and high-flying aircraft relay data back to Earth by electronic signals and advanced aerial photography. Seismographs can record underground nuclear testing. Eavesdropping devices can listen to private telephone conversations, and miniature cameras can photograph numerous data. 
<P>
<P>   In this book you will find many truths about spies.  You will have a chance to go back in history and read about famous people who spent theirs lives lurking in the shadows.  Also, many shocking accounts of how todays business' and governments can look into your life without you even knowing they are there.
