The International Astronomical Union Commission 42 ("Close Binaries") provides bibliographic information on close binary related topics through its "Bibliography of Close Binaries (BCB)" From issue no. 66 on - following a decision of the IAU Commission 42 Organizing Committee - the former publication title: "Bibliography & Program Notes on Close Binaries (BPN)" has been changed to BCB, because the "Program Notes" section of this bibliography has hardly been used any more, and it had turned out impossible to provide a reasonably complete and objective overview of all close binary related research and observing programs being currently worldwide under way. BPN/BCB is a publication appearing periodically on a semi-annual basis since several decades. All major international astrophysical journals, IAU Circulars, and some conference proceedings series are being continuously surveyed by a number of contributing editors. Close binary related articles are sampled, categorized, and listed to keep researchers informed about their favourite objects, recent results and developments. >>>>>>>> This is to announce the June 1998 BCB issue No. 66 <<<<<<<< which is now available.
