All Congress sessions are 90 minutes long. In a session of papers, 60 minutes should be taken up by the papers themselves, and 30 minutes by introductions, general to-ing and fro-ing and discussion. (Sessions in other formats may be structured more loosely than sessions of papers.)
- In a session of 2 papers, each paper should be limited to 30 minutes.
- In a session of 3 papers, each paper should be limited to 20 minutes.
- In a session of 4 papers, each paper should be limited to 15 minutes.
- In a session of 5 papers, each paper should be limited to 12 minutes.
We encourage presiders to be assertive in enforcing time limits; a well-run session with papers delivered within the time limit will be appreciated by participants and audience alike.
