As a place for storing human knowledge, libraries have the function of transmitting knowledge and spreading culture. The main function of grassroots libraries is to provide readers with book borrowing services, allowing them to understand relevant knowledge during the process of borrowing books. Due to the limited human resources in reader service in traditional libraries, one staff member can only serve one reader during the service process, making it difficult to meet the service needs of multiple readers at the same time, and it is difficult to effectively improve service efficiency and quality. Reader service is one of the important tasks of high school libraries. In the context of the information age, it is of great significance to explore the innovation of reader service in middle school libraries. A study was conducted on the reader service work of high school libraries, and strategies for innovative reader service in the context of the information age were proposed, to provide reference for relevant needs.
