From the Toolkit:
This toolkit describes our effort to conduct copyright review of books at a large scale. As you read this toolkit, you may notice some things you would change. We encourage you to identify such opportunities for improvement. This project is the product of evolving tools, staff changes, policy, and practical day-to-day decisions. The CRMS toolkit is meant to make copyright review more accessible to anyone who chooses to take up this work, but it is not meant to circumscribe the activity.
