The International Astronomical Union Commission 42 ("Close Binaries") provides bibliographic information on close binary related topics through its "Bibliography and Program Notes on Close Binaries (BPN)" , which 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 and recent results and developments. The publication can be obtained free of charge.
