The Archive file you download contains a TIFF image compressed into a ZIP archive. Your browser may be already set up to decompress these files. Commercial software to perform this is available from PKWARE, Inc., the company that invented the format. A web page from a group of people creating shareware or public domain software is available at Info-ZIP. The TIFFs are 150-dpi archival-quality color scans of the original forms and can be viewed by software like Corel PhotoPaint or Adobe PhotoShop.
