After researching grids as can be seen on my context blog ive begun to pay around with different grids. The Blue rectangles represent text on the page and how it could possibly be laid out.

As this brief is directed for teachers who need to check up on their knowledge when in a bad situation it feels appropriate to have the catalogue as a small format. Im going for A5 at the moment, this may change. This way the teacher can look at the book without too much attention being attracted.
