Abstract: In this paper, it is the first time that we apply evidence-based idea in the university library collection evaluation, according to the definition and procedure of “Evidence-based librarianship”(EBL): formulate clearly-defined, relevant to collection, and answerable questions, gain an insight into users' requirements directly; search for the objective and pertinent evidence in all available resources; critically analysis and evaluate the evidence; take full advantage of the evidence and analysis the result. Thereby, through the EBL progress above, the service quality of the university library could be improved, library decision- making could become scientific and rational, construction and development of the collection could be guided.

Key words: Library Collection Evaluation
