About: Blockchain additions, removed all the whitepapers from the list.

Why is the "Introducting Eth*" allowed in the PDF list of ebooks and the "*for dummies" series  not allowed? I do not see that rule in the contributing.md file
AFAIK, both are online ebooks links, both with an ISBN/Table Of Contents for chapters.

Either way, i replaced the first one with one that is free from offic. ibm public link
