Statistics of orbital parameters of binary stars as well as statistics oftheir physical characteristics bear traces of star formation history. However,statistical investigations of binaries are complicated by lacking or incompleteobservational data and by a number of observational selection effects.  Visual binaries are the most numerous observed binaries, the number of pairsexceeds 130000. The most complete list of presently known visual binary starswas compiled by cross-matching objects and combining data of the three largestcatalogues of visual binaries. It was supplemented by the data on parallaxes,multicolor photometry, spectral characteristics of the stars of this list takenfrom other catalogues. This allowed us to compensate partly for the lack ofobservational data for these objects. Combined data allowed us to checkvalidity of observational values and to investigate statistics of the orbitaland physical parameters of visual binaries. Corrections for incompleteness ofobservational data are discussed. Obtained datasets and modern distributions ofbinary parameters will be used to reconstruct the initial distributions andparameters of the function of star formation for binary systems.
