What we maintain
A library that doesn't go out of print
Work enters the public domain and then quietly disappears — out of print, out of catalogue, or priced past the people who'd read it. Being free in principle and being available are not the same thing.
So we keep them. We transcribe and translate public domain works, maintain them as living editions, and publish them free — mathematics, physics, philosophy, literature, history. The library grows as we go, and every title in it stays free.
- Mathematics & logicNewton, Venn, Cajori
- Physics & chemistryEinstein, Planck, Boyle
- PhilosophyAristotle, Confucius, Laozi
- Literature & poetryHomer, Dante, Austen
- History & politicsThucydides, Paine, Jefferson
- Spanish-language worksCamargo, Galdós
Maintained by Nydus Foundation on Codal. Every title is free to read online and free to print.

Why local
A free file is not a free book. Plenty of people we work with can't read a 900-page text on a phone, and shipping printed copies in is slow and expensive enough that few ever arrive.
So we print locally. Producing near the reader cuts the cost, cuts the wait, and keeps the spend inside the community rather than sending it to a distributor. It's the step that turns a maintained edition into something somebody is actually holding.
Who it's for
- Readers of all ages, from students to adult learners
- Families without reliable access to books
- Schools, libraries, and community centers
- Anyone who wants a primary source rather than a summary of one
Our approach is inclusive, needs-based, and driven by partnerships with trusted local organizations.
