Used to print some publicity information to avoid destroying the integrity of the cover. If you don't throw it away, another way is to cut it into small pieces of paper and use it as bookmarks, notes, small cards and so on. It's good to make waist paper at ordinary times. My idea is:

First, highlight key points and attract attention;

Second, expand the display space for users, and when to stop advertising at this time; Marketization, competitive pressure, etc. , put forward the need for publicity on the cover of books. Do you like it if it is printed on the cover? Will everyone tear off the cover? Therefore, one purpose of having a waist seal is to meet the needs of publicity, but also to buy it back and throw it away. The other is not to consider the feel when reading. The addition of girdle can bring a new design level, and of course it needs to be well designed.

Advertising. Publicity books. Besides publicity, what else? Personal opinion, in a word, is nothing. Feel redundant? No, it's redundant. This is determined by the characteristics of books. Books are a commodity. Need to have publicity channels. But think about it, have you ever seen books advertised on TV, radio or bus stop signs? No (Steve Jobs was advertised by Vanke Eslite). Why? Because books are low-volume products, readers in South China call them fast-moving consumer goods. Before the brand of the publishing house is established, the profit generated by each book (project) is not enough to support its advertising in other channels. So we can only advertise on the waist cover of the book. For readers, there is a lot of redundancy. Often, when a book reaches the waist, there will be a feeling that it is tasteless to eat and it is a pity to abandon it. ?
