Wikibooks:Ownership

At Wikibooks, editors are encouraged to be bold in their editing practices. When disagreements arise, writing and editorial decisions are made collaboratively. This policy explains the limitations that apply in what you can control when doing work at Wikibooks. These limitations may not apply to works forked outside Wikibooks and should not be confused for the licensing terms of use.

Ownership
By contributing, you agree not to assert authority or control over books, and to allow anyone to edit, modify, delete, and fork books at Wikibooks. You may not prevent others from editing or modifying content. This is true regardless of who started the page or who has contributed "the most" to the book. If you wish to prevent others from editing or modifying content, you may fork pages or books outside Wikibooks, where you can assert whatever editorial control over the copy you use within the licensing terms of use.

Behavior that other contributors view as ownership may not mean an explicit claim to owning the book. More frequently, the term is used to describe an unwillingness to discuss or compromise. One clear indicator of a problem is when one contributor repeatedly reverts or otherwise removes the work of other contributors. Because of the hard work involved in creating a book, strong opinions about the book's content are natural, but if you find yourself doing this, then it is time to stop and discuss. A willingness to discussion and compromise keeps everyone on equal terms in deciding what goes into books.

Wikibooks Administrators can protect pages from being edited as a deterrent to vandalism and edit warring. Page protection in this sense should not be used to exercise control over the contents of a page, and any editorial control can only be enforced by community decisions, policies, or guidelines.

Do not contribute your content to Wikibooks if you do not want other people using your contents in whatever way they want without your express permission.
