When a strong interest is detected, special thematic sessions are organized, both in the main course of the conference or as parallel sessions. The most frequent thematics sessions have been on these subjects:
- Information and documentation in mass media,
- Information and documentation in science and technology,
- Information and documentation in natural and cultural heritage,
- Information and documentation in education,
- Information and documentation in business,
Information and documentation in public administration,
Information and documentation in the Humanities - Information and documentation in non governmental organizations.
- Information and documentation for social and political development,
The conference is open for papers on any of these subjects, though an interdisciplinary treatment or perspective from the point of view of information and documentation systems is encouraged and valued.
