About Us

The mission of Runestone Academy is to democratize (make available to all) textbooks for the 21st century.  To accomplish that mission we have partnered with many institutions, the NSF, and professionals to make high quality interactive textbooks available to all students for free.  

We have over 50 textbooks available that are being used by over 75,000 students worldwide each semester.

Runestone was born from a sabbatical project of Bradley Miller in 2011, where he moved his paper textbook for computer science to an online interactive book.  This first online textbook was used in the classroom in 2012 by 60 students at Luther College.  At this stage it was called Runestone Interactive LLC.

In 2021 Runestone Interactive became Runestone Academy LTD a nonprofit corporation.  We have grown from 1 text book for 60 students to over 50 textbooks for over 75,000 students.
