The four formats provided are:

• PDF Format -requires Acrobat Reader. A free download is available at Adobe.  The printed PDF files are formatted correctly.

• HTML - this will display in your browser. You can print it using the Print option in your browser. The disadvantage is that the page breaks and figures may be in strange places. 
• Word Perfect - Requires Word Perfect version 6, 7, or 8 to print it out. 
• Zipped Microsoft Word 97 - requires WinZip (you must extract the Word 97 document and all of the graphics files) and requires Office 97 to print it out. If you have an earlier version of Microsoft Word, they have a free converter, Microsoft Word Viewer, that will let you read and print (but not edit) the files.
