"It is Yale University’s goal to make digital copies of unrestricted public domain collections available for use without limitations. Yale University will not restrict use of items digitized from its museums, libraries and archives collections which have been made openly available through the University’s electronic interfaces, and which are no longer under copyright, except where other rights or restrictions apply."
