Online Bookstore, as its name implies, is a website-style bookstore. It is a high-quality, fast and convenient way to buy books. Its scale is larger than that of ordinary bookstores. The online book mall can be used to sell books online, and can also be used for audio-visual CDs. Moreover, the book management of the website bookstore is more rational and informative. While selling books, it also has the functions of book commodity management, shopping cart, order management and membership management, as well as very flexible website content and article management functions. But the authenticity of online bookstores is the most concerned issue for consumers, which is one of the reasons why online bookstores are not accepted by most consumers.
