Copyright, Rights, and Restrictions

The resources in our directory are obtained from many sources; many protected by copyright, trademark, or related interests not governed by the Deep Time Journey Network.  If the resource is identified as having “No Known Copyright Restrictions,” the resource may be reproduced without restriction.  If there are known restrictions, the copyright holders are identified along with the resource and must be contacted for permission.  The responsibility for ascertaining whether any additional rights exist, and for obtaining all necessary permissions, remains with the researcher. See the Deep Time Journey Network’s Terms of Use and Copyright Policies for more information.

No Known Copyright Restrictions

The phrase “no known copyright restriction” means that the Deep Time Journey Network has determined, to the best of its ability based on available information, that the Content is unlikely to be protected by copyright interests and, in all likelihood, is in the public domain. However, copyright is often difficult to determine with certainty, so the phrase is intended to say that the Deep Time Journey Network is unaware of any copyright restriction, but such restrictions may still exist. In addition, even if the Content is unrestricted from a copyright standpoint, there may be other considerations that would limit your use, such as rights of privacy or publicity of the individuals featured in the images, or contractual restrictions. For these reasons, the Deep Time Journey Network makes its content available for personal and non-commercial educational uses consistent with the principles of fair use. If you decide to use the Content for commercial or other purposes without undertaking to clear all rights, you will be responsible if someone else owns the rights and the owner objects to your use.

Proper Citations and Credit
