This involves the problem of network information dissemination. A publishing house only has exclusive publishing rights, but it is generally limited to paper books (unless otherwise agreed with the author). Therefore, for e-books sold on the Internet, the copyright of the original author should be infringed. However, publishers usually have copyright laws. If the book forms the copyright of the section and the e-book is fully used, the copyright of the section of the publishing house should be infringed.
