The catalogue of spectroscopic binary orbits (SB) is a compilation of orbital data for spectroscopic binary stars which have been produced since 1969 by Alan Henry Batten of the Dominion Astrophysical ObservatoryThe SAO/NASA Astrophysics Data System [http://ads.harvard.edu/cgi-bin/search_persons.sh?cases=ignore&words=substring&fuzzy=exact&name=Batten,+A Alan H Batten entry] Retrieved February 2015 and various collaborators.{{cite journal|last1=Pourbaix|first1=D.|last2=Tokovinin|first2=A.

At the 24th International Astronomical Union general assembly, in 2000, a working group was established to take responsibility for maintenance of the catalogue, and to take it from a paper based system to an online database.IAU official website [http://sb9.astro.ulb.ac.be/intro.html Introduction] to SB9 version of the catalogue. 16 October 2003 The 9th catalogue was published in 2004.

As of 7 August 2009, the catalogue database contained information on over 2940 binary systems,{{cite book|editor=Corbett, I.

The main components of the current SB9 catalogue, as a work in progress, can be downloaded in gzipped tar ball format.[http://sb9.astro.ulb.ac.be/SB9public.tar.gz Current SB9 database, 3722 entries for version:2019-03-04 10:04:25.990702480 +0100]
