Trees, maps, and theorems is available in printed format only. Besides the lack of a reliable standard to manage digital rights, our decision to distribute a physical book only stems from a design choice: Trees, maps, and theorems is meant to be viewed one spread (two pages) at a time in high resolution, a wish little compatible with the shrinking screens on which readers seem to want to view e-books.

A printed book is admittedly more expensive to ship and more cumbersome to carry around, but we feel that the quality achieved outweighs the drawbacks. For future books, we may consider electronic formats and design the pages accordingly (as we did for our booklet on Traditions, templates, and group leaders); for Trees, maps, and theorems, in contrast, we will continue to distribute a physical, printed book only.

While we regularly receive requests for an electronic version of Trees, maps, and theorems, we also get a lot of support and understanding for our decision to stay with a physical book, especially from people who are familiar with our book's content and format.

Getting everything right down to the last detail is an undeniable success factor in our training and consulting activities, so we naturally wished to ensure the same level of attention in our book: we wanted it exactly like we thought it should be, without undue constraints or commercial pressure.

Also, we like to integrate text and layout tightly, thus optimizing entire pages verbally and visually at once. This approach requires a design freedom little compatible with a publisher's way of working.

Trees, maps, and theorems is the perfect support for our lectures, workshops, and training programs. We frequently let the participants in such sessions order the book at special conditions, via a code they can enter when ordering from this website.
