Adapted from the DARMAX Editorial Style Guide, March 2010, this guide is a quick reference tool to help PMDAR staff follow an editorial style that is consistent and appropriate for various audiences, both internal and external. The guide follows the style preferences outlined in:

The Associated Press Stylebook 2013 (Associated Press), on certain variations
Merriam-Webster’s Collegiate Dictionary 11th Edition (G. & C. Merriam Company)
Web Style Guide (Lynch & Horton, 2nd Edition, Yale University Press)

Penn’s familiar and common style takes precedence in this guide. If you do not find what you are looking for by category, use the search tool in the left sidebar. If it is not in the guide, please contact Jessica Leon, Senior Writer.

Please note that publications at other offices follow their own style guidelines, and vary from this guide.
