  The isotropy of gamma-ray bursts collected in Current BATSE catalog is
studied. It is shown that the quadrupole term being proportional to $\sim \sin
2b \sin l$ is non-zero with a probability 99.9%. The occurrence of this
anisotropy term is then confirmed by the binomial test even with the
probability 99.97 %. Hence, the sky distribution of all known gamma-ray bursts
is anisotropic. It is also argued that this anisotropy cannot be caused
exclusively by instrumental effects due to the nonuniform sky exposure of BATSE
instrument. Separating the GRBs into short and long subclasses, it is shown
that the short ones are distributed anisotropically, but the long ones seem to
be distributed still isotropically. The character of anisotropy suggests that
the cosmological origin of short GRBs further holds, and there is no evidence
for their Galactical origin.
