From http://www.atlastoolkit.org:

Atlas serves the think tank movement by providing guidance to early-stage institutes, and developing tools and programs that enhance the work of all the think tanks that share our vision. Because we have a small staff, we often cannot give our full attention to all of those who seek it. We therefore have assembled this Management Toolkit, so you can peruse some recommended readings at your own pace.
