There is a tradition in hackerdom of informally tagging important
textbooks and standards documents with the dominant color of their
covers or with some other conspicuous feature of the cover. Many of
these are described in this lexicon under their own entries. See
{Aluminum Book}, {Camel Book}, {Cinderella Book}, {daemon book},
{Dragon Book}, {Orange Book}, {Purple Book}, {Wizard Book}, and
{bible}; see also {rainbow series}. Since about 1993 this tradition
has gotten a boost from the popular O'Reilly and Associates line of
technical books, which usually feature some kind of exotic animal on
the cover and are often called by the name of that animal.
