Abstract: By building a subject branch library platform in university library, we aim to provide precise and comprehensive subject-based service to university users and assist in scientific research. By elaborating on the concept and value of the subject branch library platform, we define its architecture and use Shenyang University of Technology Library as a case study to illlustrate practical demonstration and implementation pathways. Building a subject branch library platform is an important step in exploring and practicing subject-focused services, which can fully leverage the subject-specific resources, characteristic collections, and professional information service in university library.

Key words: University library, Subject branch library platform, Subject service
