Planning for the Long Term
The basic mission of Project Gutenberg has always been to *preserve* and
*distribute* – free of charge – literary works. Over the years, the number
of works has grown in an amazing way, and has focused on using the Internet
to *distribute* books unrestricted by US copyright laws for free. All
along, that work has been made possible by volunteers and by donations by
many, many users.
As the collection has grown, the complexity of our software and systems has
increased along with those donations, and we no longer depend solely on
volunteer labor. We now employ a small but mighty staff who maintain the
plumbing that facilitates the work of our many volunteers.
The *preserve* part of our mission requires a plan for long term finances
of the organization. But having the sort of reserves that could assure our
long term existence has seemed out of reach. That is now changing. Thanks
to a bequest from a long time reader, we have started a modest endowment.
We hope that other folks might be interested in joining us to build that
endowment into a significant source of funds for our operating expenses. So
we've started a list of "Legacy Donors"
<https://www.gutenberg.org/donate/legacy.html>.
Accessibility Requirements
Title II of the Americans With Disabilities Act requires that government
funded institutions in the US must adapt their websites and electronic
resources to meet accessibility standards. These requirements are to be
phased in. Apr 24, 2026 was the deadline for providers to report on the
accessibility of their resources, and, to have a plan for fixing things
that needed fixing. On April 20, the Justice Department announced a one
year push-back of that deadline.
Since Project Gutenberg does not receive any government funding, we didn’t
think this deadline would apply to us, but there are schools and libraries
that link to our books for instruction, course lists, and user enjoyment.
Several of them have asked us for accessibility reports to help them comply
with the law. In response, this month we posted reports in the VPAT format.
VPAT stands for “Voluntary Product Accessibility Template” and the reports
available on our new accessibility page <https://www.gutenberg.org/a11y/>.
Just two weeks before the July 24 deadline, our web hosts at the University
of North Carolina asked us to assume that the ADA rules applied to us as
well. They’ve been wonderful and invaluable hosts, so we were very happy to
be able to agree!
300th anniversary of 3rd edition Newton’s *Principia*
In 1726 Isaac Newton published the third edition of his landmark work
*Philosophiæ
Naturalis Principia Mathematica* (or *The Mathematical Principles of
Natural Philosophy*, known simply as *The Principia)*. But how did it
spread?
By the 1730s, thanks in particular to Voltaire and scholars such as Pierre
Louis Moreau de Maupertuis interest in Newton was growing. A key figure in
this Enlightenment activity was Émilie du Châtelet.
<https://www.gutenberg.org/ebooks/author/56975>
Châtelet made *Principia* truly accessible at a time when Newton’s theories
were still sparking debate in France between followers of René Descartes
(Cartesians) and Newtonians. From the translation and interpretations
provided by Châtelet, along with direct tutoring, Voltaire produced “*Elémens
de la philosophie de Neuton: Mis à la portée de tout le monde*” (1733)
which brought Newtonian theories to the Francosphere.

>
Émilie du Châtelet sought to serve as a bridge between leading scientists
and the educated public. Her mastery of Latin and her understanding of
physics enabled her to make these ideas accessible.
Châtelet’s work was far more than a translation. Châtelet’s work added
extensive mathematical commentary and clarified Newton's geometric proofs
through calculus-based methods. She added explanations and personal
insights, thereby making an original and modern contribution to the
dissemination and understanding of Newtonian theories in France and beyond.
During the last five years of her life, Émilie du Châtelet devoted all her
energy to this major work, even going so far as to deposit the final
compiled manuscript at the Royal Library the day before her death in 1756.

Newton’s Principia, by Linda Cantoni
“There goes the man that writt a book that neither he nor any body else
understands.”
