💡Did you say "Open Textbook" ?

An open textbook is a textbook licensed under an open license, and made available online to be freely used by students, teachers and members of the public.

Part of the broader open educational resources movement, open textbooks increasingly are seen as a solution to challenges with traditionally published textbooks, such as access and affordability concerns.

The defining difference between open textbooks and traditional textbooks is that the copyright permissions on open textbooks allow the public to freely use, adapt and distribute the material. Open textbooks either reside in the public domain or are released under an open license that grants usage rights to the public so long as the author is attributed. (Wikipedia)
