SCI retrieval certificate report can be issued in "University Library" or "Municipal Scientific Research Information Center/Document Information Center". If your unit is a university affiliated hospital or a university affiliated unit, you can go to the "University Library" to issue this search certificate.

If your unit is not affiliated to a university, you can go to the "Municipal Scientific Research Information Center/Document Information Center" to issue it. Public libraries of this type, such as XX Library, cannot issue search certificates, so we must pay special attention to it.

These units generally have special mailboxes to receive emails with search certificates. When sending an email, you need to send specific requirements to the unit, such as whether each article is developed separately or sent together, whether it is sent by region or by impact factors, and the specific requirements, such as how much to send, should be indicated.

Before issuing a retrieval certificate, it is recommended to retrieve it first. How to search? First, enter "official website of Science", select "Web of Science Core Collection", and only check "sci-expanded-1900-present" in the "More Settings" option. At this point, the retrieved results are the papers included in SCIE.
