Where can I get Trees, maps, and theorems?

You can buy Trees, maps, and theorems exclusively
from us, through this Web site or—for large orders,
special requests, or payments by bank transfers—
by getting in touch with us at .

If you are teaching a course and consider adopting
Trees, maps, and theorems as text for it, you can
request an examination copy at .

If you are a bookstore serving a US university that
adopted Trees, maps, and theorems as textbook,
check with us at for discounts,
return policy, and the like. (And, yes, we can ship
UPS Collect from our fulfillment center in Michigan.)

Why did you decide to self-publish?

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.

What are “special order” codes?

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 Web site.

You can find a list of our upcoming public sessions
on Principiæ's Web site, under Talks -> upcoming.
