Using the method for constructing binary self-dual codes with an automorphism of order square of a prime number we have classified all binary self-dual codes with length 76 having minimum distance d=14 and automorphism of order 9. Up to equivalence, there are six self-dual [76,38,14] codes with an automorphism of type 9-(8,0,4). All codes obtained have new values of the parameter in their weight enumerator thus more than doubling the number of known values.
