How to View PDF Files (for free!)

Some documents on this site are in PDF form, which is the generally accepted best way to ensure a consistent printable, single document containing images and text. There are a number of free PDF readers available on the net:

Adobe Acrobat Reader
Adobe was the inventor of the PDF format, and this is their free viewing software. Don't attempt to download this if you only have a dial-up connection, as it is a very large download. However, you will find it on many CD-ROMs which contain drivers for your peripherals such as printers.

Foxit PDF Reader
A small 1.5Mb download, better suited for dial-up internet users.

Sumatra PDF Viewer
An extremely small and fast PDF viewer, with very basic facilities and no printing support.
