In a paper released last month by the Association of Research Libraries (ARL), Jonathan Band explains recent legal decisions that permit extensive copying and display of copyrighted material on commercial sites because the uses involve “repurposing” and “recontextualization.” In <i>Perfect 10 V. Amazon.com</i>, the Ninth Circuit of the U.S. Court of Appeals ruled that a thumbnail-sized image of a copyrighted photograph is a “transformative use” and is therefore protected by the fair use privilege by the copyright act. Similar rulings were recently handed down in favor of an artist who re-used portions of a fashion photograph, and a publisher who reproduced copyrighted posters in a book. Band’s paper “Educational Fair Use Today” is available for free download at the ARL’s website.</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="Verdana"><br class="webkit-block-placeholder"></font></div><p style="margin-top: 0px; margin-right: 0px; margin-bottom: 16px; margin-left: 0px; "><font face="Helvetica" size="3" style="font: normal normal normal 12px/normal Helvetica; "><b>Sullivan Honored by Engineering Academy</b></font></p><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Verdana" size="3" color="#0009ee" style="font: normal normal normal 12px/normal Verdana; color: rgb(0, 9, 238); "><a href="http://www.nae.edu/nae/awardscom.nsf/weblinks/JMAN-7A4L7N?OpenDocument"><u>http://www.nae.edu/nae/awardscom.nsf/weblinks/JMAN-7A4L7N?OpenDocument</u><u></u></a></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Verdana" size="3" style="font: normal normal normal 12px/normal Verdana; ">Jacquelyn Sullivan, co-PI of Engineering Pathway, has been awarded the 2006 Bernard M.

New NIH research does not have to be published for a year, and the Association of American Publishers has vowed to fight.
