Processing Books
There are many good books on Processing and you can find a nice list of them on the Processing website here 
 My two recommendations to start with: 
 
 Learning processing by Daniel Schiffmann ( http://learningprocessing.com/ ) 
 The Nature of Code by Daniel schiffmann ( https://natureofcode.com/) <-- you can do this one online 
 
 And when you have read those then you are ready for: 
 
 Generative Design ( http://www.generative-gestaltung.de/ )

Sketches / Examples
Here you find a selection of Processing example sketches form various lessons and workshops. 
 For Github links: 
 
 click on the green "<> Code" button 
 Select "Download ZIP" form the dropdown menu 
 
 The code in the repository will now be downloaded on your computer
