In reports, the FBI refers to its informants only by code numbers. Before any reports are made available to the public, revealing details about the informants are deleted. But subtle clues to their identities may remain within the text.
Valin has consented to allow the American Mafia history website to publish a collection of his ground-breaking articles online. These articles, grouped under the heading of "Rat Trap," deal with informants from major U.S. Mafia organizations, including the Chicago Outfit, the Philly Mob, the Bonanno Crime Family and the Gambino Crime Family. Six articles are in the collection at this time, and more are on the way.
Valin's often shocking conclusions are painstakingly defended through document citations (many of the related documents can be accessed online through links provided in the articles' endnotes).
