This manual describes the process of creating and detonating a wide variety of explosives. The end products include dry ice bombs and nitroglycerin. Construction of the devices described in the book is generally illegal, in addition to being highly dangerous.
According to the file's revision information, a version of TBBOM, then known as The Terrorist's Handbook (by The Jolly Roger), was compiled between 1987 and 1989. The more familiar version, built on the Handbook and other underground BBS text resources, was first posted in the early morning of August 8, 1990 as The Complete Terrorist Today. It assumed its final title with the March 31, 1991 revision.
The most common edition of TBBOM is the 1.5 release (1993), but subsequent editions are unlikely following the introduction of Sec. 1088 by the U.S. Senate on July 10, 1996. Section 1088 prohibits the distribution of information relating to explosive materials for a criminal purpose. This law also applies to any other instruction manuals possessing details on the subject.
