    <pre> Cornell University Library, Department of Preservation and Conservation is involved in a small project to compare the quality and utility of GIF and PNG file formats in the delivery of access image files. The goal of the study is to compare various attributes of GIF and PNG file formats for on-the-fly delivery purposes (generation of GIF or PNG files for online delivery from master TIF images when there is a request). Although the PNG file format has gotten quite a bit of publicity (and partial Explorer and Navigator support), it looks like the file format has not yet become very popular in image delivery on the Web. Please contact me if you know of any institutions or projects that use PNG file format, especially in the delivery of access (derivative) images. Thanks, Oya
