"Congratulations on an outstanding job. The CD will certainly work well with the invertebrate course that I teach...... Again, my congratulations and appreciation for completing a task that many of us invertebrate teachers have contemplated but put into the "too hard" basket".

-David Macmillan, Professor of Zoology, University of Melbourne, Australia

"It is a wonderful programme that performed flawlessly on my Macintosh. Its wealth of superb illustrations and thorough information on phylogeny, life cycles, and habitats of the various groups makes it a valuable resource not only for courses dedicated to invertebrates, but also to limnology and general ecology courses."

-Felix Baerlocher, Professor, Mount Allison University, Canada

"I enjoyed viewing it and am impressed by the layout and organization."

-Roy Caldwell, Chancellor's Professor, University of California at Berkeley, USA

"The CD Invertebrate Phylogeny is easy to use and very quickly allows any student or teacher access to an overview of the various zoological groups. The computer-graded quizzes allow testing of the knowledge gained. The CD is a fine initiative that does credit to Professor Williams - well done!"

-Christian Emig, Director, Station Marine d'Endoume, University of Marseille, France

"Invertebrate Phylogeny is not an electronic imitation of the traditional textbook, as it takes full advantage of current technology. The graphic navigation centered on a phylogenetic tree is a significant advance as users are constantly reminded of the evolutionary links among groups and may easily follow a branch in order to see how morphological and ecological characteristics change along it. The succinct and clear descriptions of salient characters are far easier to grasp, particularly as they are accompanied by top quality colour photographs - another leap over the traditional black and white zoology textbook. Younger students, so familiar with screen games, will find this CD far more attractive than a printed textbook."
