Over the years, Nathan P. Butler has been fortunate enough to contribute to other professional publications, usually in an unpaid advisory or interviewee capacity.
Star Wars: The Essential Atlas
(Daniel Wallace and Jason Fry)
For this 2009 Star Wars Essential Guide from Del Rey, writen by Daniel Wallace and Jason Fry, Butler developed in-universe, digital calendar dates that were then used for twelve dated maps. Dated battle map dates were derived for The Road to Coruscant, The Hunt for Zsinj, and The Thrawn Campaign. Duration dates for another trio of maps for The New Jedi Order events were derived with the help of Eddie van der Heijden. Finally, film start dates for the six live action Star Wars films were re-confirmed and provided, along with a brand new digital date for Return of the Jedi, which Butler provided.
