Making money on line book review

Scott Perkins has packed a lot into a little book and it is good , though in need of an update as in the freelance section Elance and oDesk are now Upwork. Obviously in such a small volume he cannot give long lists of websites in each category but it is a very useful pointer to what options there are to making money online ...its a good starting point and worthy of time spent on an update and expanding it .
