On the Design Rubric is states that Notebooks must be bound.
Are teams limited to one single notebook?
Should judges deduct points if you fill the first notebook and thus start a second bound notebook or just separate documentation into more than one bound notebook?
A bound notebook is not required. The revised Judge Guide for the current season includes a revised Engineering Notebook rubric in which the former 5-point bonus for a bound notebook has been changed to be inclusive of other notebook formats, including digital notebooks, and is no longer solely tied to the notebook being bound.
If a team has multiple notebooks, all of them will be judged together as documentation of a team's design process. Teams should not be penalized for this.
