Thanks for your comments. I do agree the Torres atlas is pretty good, but without being too critical, I do find the print and scale too small - making it very difficult to read. (Using it at the 'scope near impossible) Nonetheless, if I were to support one Taki's Double Star Atlas is the one that in presents information to new users. Of course, Torres atlas is great for the experience ones, Taki's perhaps for the less experience observers.
If you are searching for double stars the Navel Observatory site is usually sufficient. There are others. Another is
