Lately i have taken quite a liking to observing doubles but, having never really paid much attention to them previously, i find myself searching them out anew. Looking through Stellarium menus, i could not find a 

selector for identifying doubles. Can anyone recommend a way i could use stellarium or other means to find doubles in the spring/summer northern hemisphere?.

I can't find a way to use stellarium well for this. The problem is that it doesn't tell me the magnitude of the secondary (maybe I should play with the options), so I don't know if the double is within the reach of my telescope. I have the Cambridge Double Star Atlas and it is great. It also has the added bonus of being able to tick off the stars as I see them. It really has transformed my observing from looking at the famous bright ones to hunting down dimmer but no less enjoyable doubles. I love the challenge.

Alas, I only have it on paper form. It might be an ebook too but I've never heard of it as interactive software.

Yep theres 150,000 multiple stars listed looks like all have mags for each component and you can make observing lists in there as well.

Cartes du Ciel is able to show double stars from the WDS (Menu > Settings > Catalogs). Stelle Doppie is a nice web interface to query the WDS and generate lists you can export to SkySafari, Cartes du Ciel or Excel. Have fun, doubles are great observing targets.

Stellarium shows you the split between the components but not as far as I know their respective magnitudes.

I've found this database pretty useful:

Plus the great Star-Splitters web site of course:

The Cambridge Double Stat Atlas is very good if you can find a copy.

I have downloaded SkySafari  for my iPhone, it seems wonderful, I love the rendering of the night sky and star colors, having a look at the menu options in settings I can't seem to find a function for pointing out doubles. It is a wonderful looking app, regardless, i'm sure i'll figure out how to identify doubles through it.

If you go into settings. Find ‘stars’ in the l hand menu.  Select this and then a menu appears on the right allowing you to select doubles - image attached

If you have SkySafari 6 plus, simply click the Observe button, then click Observing Lists, you will then have a few options to select such as My Favourites, click on - ‘Import From Online Repository’ here you can chose from dozens of lists including the Cambridge Double Star Atlas to download directly to SkySafari and save in your ‘Observing Lists’ you simply select a target from the list just as you would from Tonights Best etc. 
Hope this helps.

Dean.
