Nice and easy triple-double in Peg plus bonus

Then nearby a bonus with a faint wide double-double AG423 and HJ1785 also in a 30' field of view - this one is especially interesting as the advertised data for AG423 is obviously wrong: The companion of AG423 is listed with +9.7mag but is much fainter as the +10.05mag companion of HJ1785.

I would like to explore many of the marked doubles in Sky Pocket Atlas but not sure really where to start. An example would be on chart 62. Cygnus 17 is marked a double and close by is Sigma 2576. There are several other marked doubles within a few degrees of these, how to identify?
What data bases are you using? User friendly?

PS: For my own session planning I use AstroPlanner also with the current WDS catalog plus other catalogs for orientation like Hipparco and Tycho II and UCAC4 for counterchecking the magnitudes of the components
