While most of your paper should consist of your own thoughts and ideas, it is important to include the research and ideas of others and give them credit for their work. When you do this, you are citing sources. Citing sources helps you because it:
In the field of medical research, scholars can choose between either the American Medical Association's Manual of Style or the National Library of Medicine's Style Manuel, 2nd Edition.
The reference style followed by JAMA and its related journals was developed from recommendations contained in the ICMJE Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals (formerly known as the Vancouver style) and the National Library of Medicine's recommendations found in Citing Medicine:The NLM Style Guide for Authors, Editors, and Publishers.
Citing Medicine, 2nd edition provides assistance to authors in compiling lists of references for their publications, to editors in revising such lists, to publishers in setting reference standards for their authors and editors, and to librarians and others in formatting bibliographic citations.
