For years I have enjoyed the light-hearted yet very informative books from Dummies.com. I may have even referred you to one or two depending on the subject at hand.
Dummies books aren't for Dummies - really! You should check them out. If you are a new business, learning to edit your new Drupal site, Photoshop help, video tips and tricks - even how to navigate all the social networks!
And then when you are done reading your book, go visit Dummies.com - Making Everything Easier online!
So there. I said it. Dummies ROCK!
