Tufte Style LaTeX
You might have heard of Edward Tufte. As a pioneer in data visualization, he also spent quite some time in book designs.
There is a great LaTeX project on GitHub dealing with this special design of Tufte’s books.
If you are just new to LaTeX or simply did not used it for a long time with it like me, this getting started tutorial will help you to get everything in place.
