Taki's free double star atlas also has some helpful tips (

I also use StarCalc (
http://www.relex.ru/~zalex/main.htm), CNebulaX (
http://www.uv.es/jrtorres/index.html and the excellent TriAtlas that is there) and finally CdC (
http://www.ap-i.net/skychart/) with its numerous catalogues (which you have to selectively download and activate separately) allows for cross referencing although I always struggle with its interface.
There is a bit of time involved initially in sorting it all out but it soon becomes easier.
Also don't forget the Washington double star catalogue/database (
http://ad.usno.navy.mil/wds/wdstext.html) and its web-page has some more information on various catalogues etc.
Also there is in the double star forum on Cloudy Nights (
http://www.cloudynights.com/ubbthrea...0/Board/double) which contains further information.
