A Measure of Change (1975) by Lawrence Rosenblum is a must-see eye-opener for every new arrival to Newburyport, and for those who may have forgotten the 1960s-70s. In just 29 minutes, the video documentary examines the landmark decision to use historic preservation principles for the first time in federal HUD urban renewal projects. Because of its relevance to multiple preservation topics, links to this video can be found in several places on the NPT web site, including the Preservation Resources & Links page.
