  The anisotropy of the sky distribution of 2025 gamma-ray bursts (GRBs)
collected in Current BATSE catalog is confirmed. 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 supported by
the binomial test even with the probability 99.97%. It is also argued that this
anisotropy cannot be caused exclusively by instrumental effects due to the
non-uniform sky exposure of BATSE instrument; there should exist also some
intrinsic anisotropy in the angular distribution of GRBs. Separating GRBs into
short and long subclasses, it is shown that the 251 short ones are distributed
anisotropically, but the 681 long ones seem to be distributed still
isotropically. The 2-sample Kolmogorov-Smirnov test shows that they are
distributed differently with a 98.7% probability. The character of anisotropy
suggests that the cosmological origin of short GRBs further holds, and there is
no evidence for their Galactical origin. The work in essence contains the key
ideas and results of a recently published paper (\cite{balazs}), to which the
new result following from the 2-sample Kolmogorov-Smirnov test is added, too.
