Open Textbooks & Supplements


Open licensed, freely available

Lyryx publishes textbooks and supplements with Creative Commons open licenses, available with free access to everyone, and with a variety of permissions to adapt the material. We work closely with authors and subject matter experts to develop and maintain this high-quality content while also collaborating with the community by welcoming contributions or feedback.

Lyryx offers editorial services for those courses using its software, including implementing adaptations of the content.

Lyryx also provides its educational software to support other creators of open content such as Openstax.


Open Textbooks & Supplements

  • Open textbooks and supplements are examples of open educational resources (OER); these are tools that are available to retain, reuse, revise, remix, and redistribute. OER are part of a movement that is leading the way in education. These resources are not just about cost savings and easy access to content; they’re also about collaboration and co-creation.
  • We have a variety of instructor and student supplements available including slides (PowerPoint or Beamer), solution manuals, and videos. Please see specific product pages for more information
