First, the laws of the market. To follow the principle of marketization, book suppliers will survive the fittest in the continuous development of the market, so it is also a long-term process.
Second, book products. What is needed is books that meet the reading ability of primary and secondary school students. At present, book suppliers with many books have embarked on the road of professional development, which is more conducive to the quality control of books allocated by primary and secondary schools.
Third, choose carefully. If the school can't find a suitable bookseller for a period of time, it would rather be temporarily vacant than lower the requirements for book quality, especially for the books in the book list provided by the book supplier.
Fourth, the inspection of suppliers.
Mainly the management of book inventory, regular customer communication and the satisfaction of other cooperative schools. In the information of primary school library book suppliers obtained from various channels, the relevant personnel of the school should sort out this information, preferably on-the-spot investigation, especially to be able to make accurate judgments on contradictory information.
