The marriage between books and the Internet can't wait. Reading inherits civilization, and books spread culture. Books are the carrier of social progress. All along, people's thirst for knowledge is conscious, and they will take the initiative to buy books to enrich themselves and meet their spiritual needs and practical work and study needs. Books have occupied the front-end market of reading for a long time, playing the role of cultural pusher, and naturally wearing a self-styled hat. With the development of society, reading has been uninterrupted, and people's demand for books is increasing year by year. The variety of new books published by various publishing houses is increasing every year, and the book production capacity is increasing every year. With the fierce competition in the book market, various publishers have tried their best to promote books and do all kinds of promotion for them. Doing book festival activities, holding celebrity lectures, holding cultural salons, holding new book conferences and other forms of book promotion have always been innovative actions of book marketing in publishing houses or book buildings. Compared with the traditional book marketing methods, these book marketing methods are indeed feasible, innovative and effective. Books can find some readers, but after all, these methods are still limited in strength, with small publicity coverage and vague positioning of readers, which can not meet the strong demands of publishers for the big market. With the prosperity of Internet, digital publishing challenges the traditional publishing industry. If publishing houses still hold biased book marketing concepts, want to attract people by book quality, or simply rely on traditional marketing channels to promote books, then these publishing houses will eventually hand over the cake in the market. Why? Because other publishing houses are already taking the road of book online marketing, the new channel of network makes book marketing smoother. The convenience and interactivity of the network allow publishers to directly face the target readers and make books realize accurate marketing smoothly. However, the publisher's online marketing has not really reached the strong reader coverage that the network should have. This situation can be attributed to their misunderstanding of the concept of network marketing, lack of professional network marketing talents and failure to formulate a complete network marketing strategy. Nowadays, the social division of labor is becoming more and more detailed, and publishing houses may be unable to do online marketing of books, especially the formation of online marketing teams, which consumes a lot of manpower and management costs. In the long run, the publishing house had better let the specialized book network marketing company do it, so as to ensure the effect of book promotion. If the publishing house can establish long-term strategic cooperative relations with these companies, the book promotion work can be carried out steadily. At present, some network companies are doing book network promotion. At present, there is only Xiangshang Media/full-time book online marketing in China. If the publishing house can do a good job in online marketing of books, the market prospect of books is considerable.
