Can e-books sold abroad for hundreds of years be sold?

E-books in foreign languages that are hundreds of years old cannot be sold without authorization. According to the copyright law, foreign e-books are also protected by copyright, so if these e-books are not authorized by the copyright owner, they cannot be sold at will. In addition, if the copyright of these e-books has expired, they can be freely disseminated and used. However, it should be noted that even if the copyright of e-books has expired, it is necessary to abide by relevant laws and regulations, such as not infringing on the portrait rights and reputation rights of others. If you want to sell these foreign e-books for hundreds of years, I suggest you know their copyrights first. If the copyright has expired, you can consider selling it, but you need to pay attention to the relevant laws and regulations. If the copyright of these e-books is still valid, then you need the authorization of the copyright owner to sell them.
