Producers of Software, Textbooks and Resources for Computer Science Education

January 2008 - It is with great regret that Holt Software had ceased its operation.

Unfortunately, with the end of Ontario's grade 13, and the subsequent decline in the number of students taking Computer Studies courses, we are unable to continue operations even at a smaller scale.

We would like to thank all of our customers and users over the years. It has been a privilege to serve the educational community, and we are very grateful for your support of Holt Software. We would also like to express our gratitude for the efforts that Computer Science educators have made and continue to make on behalf of their students and the Computer Studies community. Thank you.

The employees of Holt Software also thank the efforts of those who helped Holt Software's mission throughout the years. Special thanks go to Ric Holt, J.N.P. Hume, and Graham Smyth.
