ABSTRACT

Self-dual codes are important because many of the best codes
known are of this type and they have a rich mathematical theory.
Topics covered in this survey include codes over F_2, F_3, F_4,
F_q, Z_4, Z_m, shadow codes, weight enumerators, Gleason-Pierce theorem,
invariant theory, Gleason theorems, bounds, mass formulae, enumeration,
extremal codes, open problems.
There is a comprehensive bibliography.
