NEO library.org is the whole. Each library is a collection inside it, with its own scope and its own readers, ordered by one catalogue and powered by SESY.AI. It learns from the great national libraries of the world, and it is the life's work of an independent academic.

The flagship and prototype of the system. It orders Maya science and culture: base-20 mathematics, the Tzolk'in and Haab' calendars, astronomy, languages and art, as a living body of knowledge.
The cultures, languages and heritage of Mexico, from the Mexica and the oldest traditions to contemporary creation. It follows the example of the Biblioteca Digital Bicentenario, which opened more than 700 old and out-of-print titles "with just one click".
Sánchez González, José Fernando (2014), sec. 3.3, p. 71 · translated from Spanish
The great Maya forest as a living collection of the Mayan Library: the forest, its ecology and the natural knowledge carried by the people who live in it.
The universal hub of the system. It gathers contemporary science, technology, economy and the humanities with ancient knowledge, so that any subject can be found in one place and related to every other.
Knowledge ordered by bioregions: watersheds, mountains, forests, coasts and islands, on every continent. Territory becomes a facet of the catalogue.
The fire circle of nature, science and reconciliation. Elders are recognized as Professional Wisdom-Keepers; recordings are made only with consent, with an honorarium and a copy for every elder.

The programsLearning from the great libraries
The great libraries of our four languages, and the world library they helped begin. Each one leaves a lesson that NEO library.org carries forward.
Washington, D.C. · United States
Founded on 24 April 1800, it is one of the largest libraries in the world, with more than 170 million items. There Henriette Avram created MARC, the machine-readable catalogue record, and American Memory (1990) grew into the National Digital Library (1994).
The lessonA catalogue that machines can read.
Mexico City · Mexico
Decreed in 1833 and opened in 1867, it lived in the former Templo de San Agustín from 1884. Part of UNAM since 1929 and kept by its Instituto de Investigaciones Bibliográficas since 1967, together with the Hemeroteca Nacional, it has stood at the Centro Cultural Universitario since 1979.
The lessonThe university keeps the memory of the nation.
Ottawa · Canada
Created in 2004 by joining the National Library (1953) and the National Archives, whose roots go back to 1872. One institution keeps the published and the documentary heritage of the country, fed by legal deposit.
The lessonLibrary and archive, one memory.
Rio de Janeiro · Brazil
Founded in 1810 from the Portuguese royal library, rebuilt after the Lisbon earthquake of 1755. With about nine million items it is the largest library in Latin America, and legal deposit has fed it since 1907.
The lessonA collection can cross an ocean and begin again.
Paris · France
Its origin is the royal library that Charles V gathered at the Louvre in 1368. Since 1997 its digital library, Gallica, has opened millions of documents to every reader online.
The lessonOpen the treasure to every reader.
UNESCO · Library of Congress · the world
Launched at UNESCO on 21 April 2009 with the Library of Congress and libraries of many countries, it presented treasures of every culture in several languages. Its collection now lives at the Library of Congress.
The lessonOne library for all humanity, in many languages.

The life's work
The national libraries were built by states over centuries. NEO library.org is the life's work of Librarian Joséf Sánchez Coach as an independent academic: a new kind of library that one librarian, working together with the artificial intelligences of the world, can design, build and keep open, and that every reader can help to grow.
In 2014 his thesis named the Universal Digital Library a dream still to be built. This is how he builds it.
