Study Notebooks

Study notebooks on the backend work that interviews and production both care about. Each one is built around a single question, because one question worked properly teaches more than a survey does. Written to be printed and written on.

How to get one

Sign in, open the notebook you want, and it stays open: every page, every edition, nothing withheld and no clock on it. The account is there so a download belongs to someone, not to charge you.

Three editions

Reading.
A4 portrait, no annotation margin. For reading on a screen.
Print.
A4 with a wide outer margin. Made to be printed and written on.
Tablet.
16:9 landscape, fills a tablet screen. Vector text, so note apps draw it rather than rasterise it.

The Discord is where the working notes go: what is being written next, corrections, and questions from whoever is reading the same notebook as you.
