This is the second edition of a post that I will be doing on a weekly basis titled, "Saturday Sourcebook."  If you missed the first edition, or want the in-depth explanation of why I am making this a weekly post, check out the original Saturday Sourcebook post below.  My main objectives are to narrow down the best innovation links of the week, provide real-world examples of the concepts I talk about in my book and to give my readers something to read on the weekend when few people are publishing content.  Without further delay, here is the Saturday Sourcebook, volume #2:
