There are many books available; some are listed below. However, the Work cannot exist in isolation and for those seeking, it is necessary to find a group of people working directly with the ideas and methods expressed by Mr. Gurdjieff. A good exposition of the ideas is contained in Ouspensky's In Search of the Miraculous.
In Search of the Miraculous - Fragments of an Unknown Teaching by P. D. Ouspensky
Ouspensky spent nine years with Gurdjieff, during which he recorded Gurdjieff's teachings as presented to his pupils. It is probably the most concise record and explanation of Gurdjieff's philosophy, psychology and cosmology and provides a comprehensive introduction for people new to the ideas. ISBN 1-85063-090-09

The Reality of Being - The Fourth Way of Gurdjieff by Jeanne de Salzmann
As his closest pupil, Jeanne de Salzmann was charged by Gurdjieff with carrying on his teachings of conscious evolution.
