Free Data Mining Books and Distinction Advice

From Data On Focus.  A list of links to free data mining resources. Nicely done.  No excuse these days for not getting lots of information on the subject.  Likely lots of variance in value and need for preparatory information.    Is it data mining or machine learning or data analytics?   There is great overlap, depending upon if you are talking to an engineer, computer scientist, statistician or marketer. Each can learn from the other, and sometimes even does.   Still hoping to get more executives involved.
