Buying out novels and signing contracts were two common copyright management methods in online writing. The specific meanings were as follows: 1. Buy out the novel: A novel purchase was when the author bought the copyright of the novel and created, published, and sold it independently without cooperating with any publishing house or online platform. The buyer could decide on the direction of publication and sales channels of the novel to better control the creation and marketing of the work. A novel purchase usually required the author to pay the copyright fee and sign a copyright transfer agreement to ensure that the buyer could fully control the copyright content and profits. The novel purchase was applicable to personal creations, small publishing houses, or online platforms. 2. Contract for the novel: A novel contract referred to the author signing a contract with a publishing house or online platform to become an author of the organization or platform for the creation and distribution of the novel. The contractor had to transfer the copyright of the novel to the organization or platform according to the contract and create and market it according to the content agreed in the agreement. The contract usually included terms such as copyright transfer, remuneration, publishing, distribution, marketing, etc. to ensure the balance of interests between the author and the organization or platform. The contractor had to read the terms of the contract carefully and create and market according to the contents of the agreement. Buying out and signing a contract were both common copyright management methods in online writing. Different choices were suitable for different authors and creative situations. The choice of method depended on the specific situation and his own needs.
