• Depth of Field Outside the Box by Richard F. Lyon
  Article on depth of field, presented in an unusual way, but probably simpler in the end,
  Abstract :"It is not necessary to know the focal length and f number of a camera lens to compute a depth of field, and indeed formulas that use the “outside the box” parameters, field of view and entrance pupil diameter, may be easier to understand and reason with. The often confusing issue of how to choose an acceptable circle of confusion diameter is simplified in this approach as well, and is tied more simply to the resolution of human vision, typically as a nondimensional criterion such as 1/1500 of the image diagonal. [...] As far as I can tell, however, this approach has never been fully and carefully articulated, and there is ample evidence of historical and modern-day confusions that it could help to clear up."
  
  
• An Introduction to Depth of Field (PDF) and  Depth of Field in Depth (PDF) by Jeff Conrad for the Large Format Page 


• Camera Focal Length and the Perception of Pictures by  Martin S. Banks, Emily A. Cooper, and Elise A. Piazza
  Article giving a rational explanation for the normal focal length.
  "...photographs of scenes captured with short-focal-length lenses appear expanded in depth, while those captured with long lenses appear compressed. These effects can be seen in still photographs and video.
  ...
  A rule of thumb among professional photographers is to use a focal length of 50mm for standard 35mm film (...). Photography texts offer explanations for this rule's efficacy, but they are either vague or merely restatements of the phenomenon."
