Inserting the same document with endnote into the same document can display two locations, as long as the document you get is in different locations. EndNote can directly connect to thousands of databases and provide universal retrieval methods. The application of EndNote is not limited to the writing of submitted papers, but also plays a very good auxiliary role in the writing of graduate papers. Online literature search: directly search related literature from the Internet, import it into Endnote's literature library, and establish literature library and picture library: collect, manage and search personal literature, pictures and forms. Customize the manuscript: format the quotations and charts directly in Word, and use the manuscript template to directly write articles that meet the requirements of the magazine. Citation arrangement: It can automatically help us edit the format of references. Endnote can access most of the literature databases in the world conveniently by using the information acquisition protocol of Z39.50, and store the information of connecting and searching these databases in the form of "connected files" and provide them directly to users. The settings of the connection file can be created or modified by yourself.
