Here is an audio/video upload of a presentation called “Narcotics Anonymous: The Early Story.” I’ve listened to it time and again. This fascinating talk has been given at NA World, and on various continents and regions of the globe.
My other favorite is this bit of writing titled “Narcotics Anonymous: Its History and Culture.”
I strongly encourage everyone to check these resources out. Personally, I’m waiting for the book.
As an aside, I’ll add that the work of gathering this information is itself quite amazing.
