The deep integration of culture and tourism is the new mission faced by domestic public libraries in the new era. With the development of study tour, it is a direction for public libraries to provide service of study tour from a practical perspective as a measure to integrate culture and tourism. This paper analyses the specific practices of public libraries in U.K., the United States and Japan in such projects as “Off The Map” “Every Kid in a Park” “Museum Start i-Ueno” and Glasgow women’s historical travel. It summarizes four lessons drawn from the practice, namely, using technology to promote service, valueadded study tour experience, reflecting product differences and developing characteristic trips. Finally, this paper puts forward four suggestions to promote libraries in carrying out study tour services from the actual situation of domestic public libraries: to establish a correct concept of integration and develop with the help of synergistic advantages, to provide study tour reference and add value to the experience of study tour, to refine the library’s characteristic elements to make itself a study tour destination, and to develop from tourism to study tour and build the brand of library activities.
