Gamma-Ray Bursts from the BATSE catalog, available at www.batse.msfc.nasa.gov, have been divided into "classes" according to duration, hardness ratio and galactic latitude. Some selection criteria have been adopted, in order to avoid data affected by very large measurement errors and/or strong detection biases. The well known "bimodal" distribution in burst duration is quite evident, as well as differences in the intensity distributions of bursts with different hardness ratios and a weak indication of anisotropy both for the softer and harder events.
