When creating James O'Rourke's article a decision was made to present them in three different ways.  Below are links to the three versions presenting the same information. 

Endnotes

Links in the article itself

All information put into a PDF file

Each have their advantages with endnotes being used to present the information in a Research Format.  This article has not just endnotes but links to the actual documentation.  The online version is much more user friendly.  Done this way a person wouldn't have to search for all of the information as it's already there, just click and go.

The second version is linking to the information presents the same information but you don't have to look to the endnotes. 

The third way to present the information is to put it all into one PDF and use a table of contents then the actual article and then all of the information together.
