“In the years since OpenStax published its first textbook, our offerings have matured and our platforms have evolved. We’ve done our best to listen to our adopters and work with our authors to develop a balanced updating, improvement, and revision strategy.

OpenStax revises books, creating formal new editions, only when it is pedagogically necessary to do so. The process is extensive and requires significant resources. Between new editions, we make updates and improvements based on errata submissions, suggestions from adopters, ideas from contributors, and specific reviews for diversity and representation. Below I’ll outline the approach to each.

First, a brief overview of our development process: OpenStax textbooks are developed and peer-reviewed by educators to ensure they align to the coverage and sequence of their respective courses, keeping in mind common learning outcomes and points of emphasis from academic communities and discipline organizations. Our development process includes thorough editing, careful review, and detailed quality assurance measures. Then, after a book is published, we begin the process of maintaining and improving it.

And second, as discussed below, the online view of the book — as opposed to the PDF or other formats — is the one we recommend because it is always the most up-to-date, the most accessible, and includes features such as notetaking and highlighting. Also, the OpenStax course cartridges, available for several learning management systems, link directly to the online and most updated version….”
