18 Jul 2013-2015 Discipline Now Available
From this link, you can download the 2013-2015 Discipline in PDF and also view it online.
We do not print hard copies of the Discipline. Since it’s up for revision every two years, that’s not enough shelf-life to make it economically feasible. Since 2005, the Discipline has been available only in electronic form. But you can download it and print out a copy for your own use.
