As not all sections are complete, the Editors of the Handbook would like to hear suggestions for new questions and comments on the existing sections.
If you are dissatisfied with your performance, consider reading the relevant areas in the Handbook of Informatics or in the new Second Edition of Medical Informatics. Both are featured in our recommended reading section.
