Citing Medicine 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.
 
Follow this format when typing your bibliography:
    • Start the reference list on a new page
    • All references are listed alphabetically by author's name or publishing organization if author's name is not included
    • Center the word References (Reference, if there is only one) at the top of the page
    • Double-space all reference entries (unless to otherwise by your instructor)
    • Indent the second line of your reference five spaces
