We’re in the process of making many of the videos, audio files, books, images, and other content created over the years available on our website. We’re happy to provide as much as we can for free, as well as additional content for our members. If resources like these are of value to you, please consider becoming a member. Your membership supports the growth of our society, as well as our efforts in creating new content and preserving the historical work that brought all of us to this point in the first place.


Both content creation and archival work are continuous endeavors. We simply do not know everything that is out thereIf you have videos, documents, pictures, audio files or anything else related to charting and Precision Teaching you would like to share, please email us at [email protected]. We may be able to help you restore, edit, digitize, and share that material with up-and-coming generations of charters.
