Since the early 1950’s, data has been collected on North American mission organizations. It began as a simple directory of agencies and grew into a handbook published every 3-5 years with over 600 pages. It went through many changes over the decades. Missio Nexus published the last print copy in 2016 – the 22nd Edition of the North American Mission Handbook. It recorded data on more than 900 mission organizations across the United States and Canada.
