APA citation style refers to the rules and conventions established by the American Psychological Association for documenting sources used in a research paper. APA style requires both in-text citations and a reference list. For every in-text citation there should be a full citation in the reference list and vice versa.
APA论文写作规范是由美国心理学会为论文引用文献（the American Psychological Association )确立的一整套标准格式。包括文中引用和文末引用文献清单。每一个文中引用对应一个文末一个完整的引用，反之亦然。
The examples of APA styles and formats listed on this page include many of the most common types of sources used in academic research. For additional examples and more detailed information about APA citation style, refer to the Publication Manual of the American Psychological Association and the APA Style Guide to Electronic References.
Also, for automatic generation of citations in appropriate citation style, use a bibliographic citation management program such as Refworks or EndNote. You can find more information on this in our Citation Management page.
