As for the Raphael Lemkin Collection, the AJHS had permission from Lemkin’s heir to make digital reproductions of the collection accessible. Among the selected materials was much correspondence from third parties. They were letters from various activists to people, committees or organizations that had the power to influence the United Nations or various governments to adopt and/or ratify the convention. The letters were protected by copyright. AJHS and the Center started to contact copyright holders and permission was granted whenever possible. We also reviewed the four factors of “fair use” and concluded that the factual nature of the correspondence and our intended use allow for making the letters accessible to the public for “fair use” (see Fair Use, 2009). Each digital folder containing letters was associated with a "click through" copyright notice, outlining the allowed terms of “fair use” such as that no use other than research, teaching, and private study is allowed without prior permission from the copyright owner. Copyright owners not properly identified, or any user with information on the copyright status of a particular work, are asked to contact the Center and AJHS so that appropriate information can be provided in the future. Every user desiring access to the digital materials must agree to these terms by clicking on a button before gaining access to them. The fair use information can also be found in the descriptive metadata record that is attached to each letter and at the bottom of the CJH Digital Collections website.
