OpenStax
OpenStax is a nonprofit education initiative of Rice University that publishes free, openly licensed textbooks and related materials for introductory courses. Subject matter experts write the textbooks, which are peer-reviewed for accuracy and updated regularly. Books can be read online on the web, Android or iOS, or downloaded as free PDFs; low-cost print editions are also offered. Most titles are accessible without an account, although a small number require sign-in. Students can highlight, take notes and create study guides, with a free student account required for some features. Educators with a free account can access test banks, PowerPoint slides, solutions manuals and customization tools. OpenStax Assignable lets instructors assign readings, assessments and supporting materials through an LMS, with automatic grading and gradebook synchronization. It supports LTI 1.3 and Blackboard, Canvas, D2L Brightspace and Moodle. Textbooks cost nothing. Assignable starts at $15, paid once, billed per student per semester; instructors use it free, and a two-week trial begins on the first day of access. Institutional pricing is by contact.
