Write the reference number of your citation. Your references need to be listed in the order you cited them and numbered accordingly. Your first entry starts with "1" as your reference number, your second reference starts with "2," etc. Put a period after the reference number.
Write the author's name immediately after the period. Write the author's last name, followed by his first initial. Multiple author names need to be separated by a comma. If the paper has more than six authors, only list the first six, and write "et al." after the author's name.
For example, for referencing a paper written by John Smith and Elizabeth Baker, you would write:
1.Smith J, Baker E.
Write the title of the paper. Only the first letter of the first word in the title should be capitalized.
Write the title of the journal in which the paper is published.
Use a single space, then write the year the paper was published, followed by a semicolon.
Write the volume number, then issue number of the journal. The volume number comes immediately after the semicolon. Place the issue number in parentheses immediately after the volume number. After the parentheses, place a colon.
Write the page number(s) from which your citation comes. For example, if you referenced a 2001 paper titled "The Effects of Smoking on Lab Mice," by John Smith, from page 40 of "Journal of Medical Science" volume three, issue four, your reference would look like this:
1. Smith J. The effects of smoking on lab mice 2001;3(4):40
Write your citation as it appears in your reference. If you quote directly form a source, place the entire citation in quotation marks.
Write a reference number after your citation. Your reference number should come immediately after the part of your text to which the reference applies. The reference number needs to be in superscript form or in round brackets after the citation.
Use the same reference number for all future citations that reference the same source. Your first reference will use the reference number "1." If your next citation references another source, that citation's reference number will be "2," but if you reference your first source again, that citation's reference number is "1" as well.
