This is good news (if a bit old at this point--I'm always behind).
This could be an excellent solution to the seven missing tribunal books (The Missing 5E Tribunal Books). Release them on pdf and print-on-demand, so no large printing expenses are incurred. Combine that with the idea of opening them up to submissions by those who have already put a lot of work into them a la the recent Spanish Iberian tribunal book, as discussed in the thread above, and voila, the only thing required of Atlas is some editing and final formatting.
Would also love to see the Grand Grimoire available in this format, with some nice cover art matching the rest of the game.
