The Brethren (also see Tabula) have compiled all essential information about their organization and its enemies in six “books” identified by the color of their binding. It can not be established if the books ever existed as printed volumes. The current books are loose-leaf, three-ring binders that easily accommodate new or altered data. Individuals working in different levels of the organization can receive versions of the books that omit certain pages. 

There have been underground versions of the six books, published by Max Fulmer in 1968 and Enrico Granelli in 1985. (Note: Fulmer has also written books about the Illuminati and the Masons.) On close analysis, these works appear to be fictional creations written for commercial objectives.

The archivist believes that no reputable researcher has actually read the books and all statements concerning them are conjectures based on secondhand accounts. That being said, a conclusion can be made regarding the general contents of four of the six books. 

The Green Book is about the Travelers. The Red Book is about the Harlequins. The Blue Book is a short history of the Tabula. The Orange Book is about the Panopticon and the Tabula’s long-range effort to control the attitudes and behavior of the world population. There is no reliable description concerning the contents of the Silver and Gold books.
