d completely rebuilt. Most collections contain the data published to t
he end of 1995, taken from more than 2500 papers. We have updated the
Master Index which now contains information for over 207500 stars and
components. Public access to the data is provided through the World Wi
de Web at http://obswww.unige.ch/gcpd/gcpd.html. A connection has been
