a selective guide to various free and open source software tools for a variety of digital media applications. This is an attempt to provide a first port of call for those looking for free and/or open source applications on the Internet. There is a bewildering array of such software and, as a result, we cannot hope to make this directory comprehensive. In addition, the almost daily changes in existing applications and the constant arrival of new ones means that the accuracy of information in these tables can’t be guaranteed. What this directory can provide is an easy way into the maze of applications on the Internet and a useful list of some of the most popular tools available. A quick glance at the tasks in the left hand column will immediately lead to one or more appropriate applications along with information about what machines it or they will work on.
