Since it has now been officially announced in the OUP catalogue, this seems an appropriate moment to publicize the forthcoming appearance of "Sketches of an Elephant: a Topos Theory Compendium" (volumes 1 and 2) by Peter Johnstone published by Oxford University Press. Both volumes are scheduled to appear in June 2002. Volume 1 (ISBN 0-19-853425-6) contains 720 pages, comprising Part A: Toposes as Categories and Part B: 2-categorical Aspects of Topos Theory. Volume 2 (ISBN 0-19-851598-7) contains 880 pages, comprising Part C: Toposes as Spaces and Part D: Toposes as Theories. (Volume 3, comprising Part E: Homotopy and Cohomology and Part F: Toposes as Mathematical Universes, is still in preparation.) Volumes 1 and 2 are priced at 100 pounds each if bought separately, or 175 pounds if bought as a set (under ISBN 0-19-961138-6). 15-Feb-2002 17:49:25 -0400,2880;000000000001-00000000
