If I decide to self-publish a book what happens to the copyright?
Is there a way to prevent others from claiming copyrights for a book published autonomously?
Are there OS licenses specifically tuned for books?
Here's a careful reminder that "public domain" is not a worldwide thing ^^; in fact, very few countries have a public domain.
In some cases, if you try to publish something as "public domain" from a certain country, it is invalid - because their judiciary does not define public domain as anything.
It maybe considered public domain, until you die and someone wants that copyright, in which case the family takes precedent over the estate - full stop.
There's a difference between countries that have common law (US and UK) and those that have civil law (the Nordics), so yeah.
But CC is valid license pretty much everywhere, with a few exceptions.
Do I have to provide my name? Can I ask that my name be removed?
As a licensor, you may choose to receive under any name that you wish, such as a pseudonym or pen name, or you may choose not to be credited by name at all, and to publish anonymously. You do not have to be credited under your legal name. Most jurisdictions permit this, but you should check to be sure this is valid in your jurisdiction.
the author can still sell the work, the NC prevents other people from profiting off of it without explicit permission (this does not prevent exemptions, work can still be sold under cc-by-sa as an exemption)
