Retrieval Certificate

The retrieval certificate service is generally used for various scientific research evaluation activities. Based on the literature information (such as titles, author names, affiliation names, journal names, etc.) provided by the client, the professional librarians carry out an accurate literature search in Web of Science, Scopus, CSCD, CSSCI, CNKI and other databases. The detail about the literature indexed and cited by other articles in specific database will be retrieved. Some new indicators like impact factors and box plot of JCR journals, subject percentile, and ESI highly cited papers can also be provided on demand. A retrieval certificate will be issued in accordance with the search results.
