Adobe Acrobat Reader

Adobe Acrobat PDF (portable document file) files contain all the information needed to fully describe a document: fonts, graphics, and even colors. It is a very useful way to exchange files that have such features, such as working papers. The IRS even uses PDF files to distribute tax forms through the Internet. To read PDF files, you need an Acrobat "reader." Adobe makes readers available freely at this site (they generate revenue from the software that creates PDF files). It is easy to configure web browsers to automatically invoke readers when they encounter PDF files.
