One of the essential tasks for professors, students, and researchers is writing papers, theses, dissertations, textbooks, and scientific reports, etc. However, the process of searching, managing, and citing documents still has many limitations. A significant number of authors still manually cite and manage their documents or use the built-in citation feature in Word software. These methods are unprofessional and inconvenient. In this article, we would like to introduce Endnote software. It is a management, search, and citation software for reference documents that we and many domestic and international researchers have been using. It is convenient, professional, and easy to use if we are interested in research.
