The Acrobat PDF format allows you to download, view, search, and print, while maintaining the original look of how the document was created (ie looks same as a word processed document). This format is widely used on the World Wide Web (usually for full-text documents); it is a wise use of time to go ahead with the download and viewer configuration.
If you don't have a copy of the free Acrobat Reader, you can download it from the Adobe Website
