The Biggest and Most Authoritative Library of Open-Source UX Design Resources

Open-Source, Open-Access Literature

The democratization of design knowledge is at the very heart of our mission. That’s why—over 21 years after we started—we will never stop bringing leading designers, bestselling authors, and Ivy League professors together to create open-source, free-to-access textbooks on UX design. This is the world’s most comprehensive compendium of design knowledge, made available to everyone around the world.

The Encyclopedia of Human-Computer Interaction, 2nd Ed.

Free textbooks written by more than 100 leading designers, bestselling authors, and Ivy League professors. We have assembled our textbooks in a gigantic encyclopedia, whose 4,000+ pages cover the design of interactive products and services such as websites, household objects, smartphones, computer software, aircraft cockpits, and what have you. Name an item of design interest, and you'll probably find it discussed inside.
