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.
