The contributors and links are predominantly North American, and even more predominantly English-speaking. Though the topics of women and gender in other ancient societies, such as Egypt and the Near East, are not ignored, the focus is overwhelmingly on Greek and Roman antiquity. There is little here to help out researchers on women in ancient China, India, Mesoamerica, etc, and likewise little on general feminist theory and anthropological studies of gender. These limitations mean that professional researchers will soon find themselves in need of looking beyond Diotima, a fact which makes the site's usability by students and inexperienced researchers even more important. For this reason more emphasis should perhaps be given to selectivity than to comprehensiveness and eclecticism.
Quality control is also an occasional problem.
Although the vast majority of the material Diotima has to offer is scholarly and reliable, there are some exceptions. The instructor who sends his or her students to Diotima cannot omit giving them careful instructions about the evaluation of Internet sources. The interface design of Diotima is impeccable throughout. Information is laid out in large, attractive type on a plain white background. There are no frames and very few graphics.
