Not sure if a super late-ish response but I found this online a while ago for GP logbooks:
The logbook
The logbook is meant to be a record of your involvement in the development of your Group Performance. It should be with you all the time and you should record each day’s work. Remember to:
- date it
- describe what your group did that day and how you felt about it
- write what problems you are having and what you are doing about those problems
- include any staging or costume ideas you have
- record what you are learning from working with the group
- include any materials you use: brainstorming notes, articles, photos, poems, songs, interviews, drawings and quotes
- record any advice or comments you get from other people
- record all ideas and material you create and explore, even if eventually you don’t use them in your performance
- include a record of the final product.
