While Muidokan produces content through its own research, it happens to be part of a larger, worldwide movement including many honorable researchers, translators, instructors and enthusiasts. All of those people and their organizations have been contributing greatly to taking karate and traditional martial arts to a greater level of understanding, and a respectable part of the very studies carried out in Muidokan have been in one way or another benefited by the works of many of them. Among other by chance not included here (it is an ever-incomplete list), Muidokan greatly recommends the following resources, in no particular order:
