In a review, it mentioned that I was not compliant with the D20 system in my books due to my use of MM, DMG, and PHB. I have read this as a criticism for others' works as well, so I decided to post straight from the source.
For those who don't know or haven't looked lately, the D20 System Guide Version 3.0 on the Wizards web site says
"You may refer to the Dungeon Master’s Guide as the DMG, the Monster Manual as the MM. You may cite the Player’s Handbook by title, or as the PHB. You may cite the Psionics Handbook by title. You may cite the d20 Modern Roleplaying Game by title. You must not cite page number references, because pagination may change in future printings. You may cite chapter, heading, and subheading titles from the DMG, the MM, the PHB, the Psionics Handbook, or the d20 Modern Roleplaying Game."
Therefore, anyone using DMG, MM, or PHB in a D20 publisher's book is compliant.
