There are two different files for each illustration

A 72 ppi GIF file, suitable for screen viewing is accessed through the thumbnail image

An eps file, suitable for downloading to be printed or edited is accessed through the "eps file" link. Most files are Adobe Illustrator 6.0, exceptions are noted. These files have been compressed with GNU's gzip utility. If your web browser defaults to a screen display of the file, turn on the "Load to local disk" option before downloading.
