There are now several sources for Pali Language texts.

There is an excellent CD-ROM out there now from the Vipassana Research Institute  http://www.tipitaka.org/.

A conversion program for this CD-ROM is available at http://freepali.org/ together with a variety of fonts and character maps.

An on-line version of the Canon is at the IBRIC pages on this site
