The surveys which are the chief foci of this meeting are almost exclusively concerned with recent and upcoming electronic surveys. But the practice of surveying the night sky is not new; some of the first coordinated observatory activities involved surveys, of various hues and sizes, and for many decades the IAU paid tribute to that activity by supporting a special Commission for it. The wealth of past surveys is described briefly. Though now regarded as limited in quality, early surveys carry date-stamps which enable their contents to add usefully, sometimes critically, to modern science.
