Information Circular
The lists of new binaries and orbital elements which have traditionally comprised the Circulars were recently supplemented by bibliographies of recently published binary star papers. Both paper and electronic mail versions of the Circular are published by Drs. Docobo and Ling. Contributions to this most worthwhile publication should be sent to the authors at joseangel.docobo@usc.es or josefina.ling@usc.es, respectively.
We join all binary star astronomers in expressing our gratitude to Drs. Muller and Couteau for their major efforts over the past 40 years, as well as to Drs. Docobo and Ling for their continuation and expansion of this effort. Thanks should also go to the Universidade de Santiago de Compostela, for their financial assistance in the publication of these Circulars.
