The copyright of online novels could be registered in multiple places, depending on the genre of the novel, the legal provisions for copyright protection, and the rules of the location. The following are some common locations for registering online novel copyrights: 1. National copyright bureau: The national copyright bureau is the competent agency for copyright registration. For copyright registration of online novels and other literary works, you can go to the national copyright bureau for registration. 2. Provincial, autonomous regional, and municipal copyright offices: The copyright offices of different provinces, autonomous regions, and municipal governments also have their own registration agencies. You can go to the local copyright office to register. 3. Web novel websites: Some web novel websites also provide copyright registration services. If the copyright of the novel belongs to the website, you can go to the website to register. It should be noted that copyright registration was not the only way to protect the copyright of online novels. Other measures needed to be taken to protect the intellectual property rights of the novel, such as taking legal measures to investigate the violation.
