Creative Commons and the Four-to-Free (42F) Guarantee

Each CommonsWare book edition will be available for use under the Creative Commons Attribution-Noncommercial-ShareAlike 4.0 license as of the fourth anniversary of its publication date, or when 4,000 copies of the edition have been sold, whichever comes first. That means that, once four years have elapsed (perhaps sooner!), you can use this prose for non-commercial purposes. That is our Four-to-Free Guarantee to our readers and the broader community. For the purposes of this guarantee, new Warescriptions and renewals will be counted as sales of this edition, starting from the time the edition is published.

This edition of this book will be available under the aforementioned Creative Commons license on 1 January 2023. Of course, watch the CommonsWare Web site, as this edition might be relicensed sooner based on sales.

Note that future editions of this book will become free on later dates, each four years from the publication of that edition or based on sales of that specific edition. Releasing one edition under the Creative Commons license does not automatically release all editions under that license.
