e-books

Personal journeys in the age of digital interdependence will benefit from a new generation of reference works: e-books that include the description of all classes or nodes in the classifications that matter to public sphere literacy and information integrity. 

These e-books are convenient for exploring classifications and when you have to look up the hashtag for a specific economic activity or function of government, a product, a service, a language, or a local government unit.  

By purchasing an e‑book, you help us continue our work and keep all wikis freely available to everyone.

All e-books are published via Leanpub which handles payments and supports publishing in many languages.

We encourage volunteers and partners to publish translations of the reference e-books. Every translation expands access and strengthens the portfolio.
