    <pre> I have read that the Unisys patent on LZW compression will expire soon (ca. 2003). If this is so, I am curious whether readers of this list would consider TIFF with LZW compression a viable archival file format for images. The question in my mind is whether we expect the LZW format to be widespread enough that TIFF/LZW files can be accessed and read in the relatively far future. If not, are there other lossless compression formats that might be considered for long-term storage?
