AMA 10th Referencing Guide: Lecture Notes

Referencing guide for the 10th Edition for AMA Style

In text numbering

Superscript numbers

The numbers in text are in superscript1 and occur at the end of the clause in which you used the information.  They occur outside “quotation marks,”2 commas,3 (parentheses)4 and full stops.5 However, they occur inside semicolons6; and colons7:

Do not leave a space between the last letter or punctuation mark and the number.

Re-use numbers for the same citation

Citations should be numbered sequentially – that is, the first source you cite is 1, the second source is 2 and so on.

However, once you have given a source a number, it will keep that number throughout your paper. So, if you use your first source again, no matter how often you use it, it is still 1.

Citing more than one work at a time

Use commas to show that more than one work is being cited, and use hyphens for several works that would be numbered sequentially:

These side effects can have implications for the patient's mental health, as numerous studies have shown.1,3,6-9

Relationship between in-text citations and reference list

Your reference list follows the order of the numbers used in the text. The first source you cite in the text is 1 and the reader will look for number 1 in the reference list to find the full citation; the fifth source you use is 5 and the full citation is listed at number 5 in the reference list (and so on).

Using author's names in-text:

If including an author in the text of a sentence, use the surnames of authors and add the citation number after the author’s surname. 

  • For one or two authors list all names
    • Smith1 reported on the survey.
    • Smith and Watson2 reported on the survey.
  • For more than two authors list the first author and follow by et al
    • Smith et al3 reported on the survey. 

Lecture notes

How you cite lecture notes and handouts depends on whether they are available online or were distributed on paper.

Online Lecture Notes:

If the notes/handouts are available online through LearnJCU, cite them as a web object. Include details in [brackets] after the title, if it is necessary for clarity.

  2. TV1101 - week1: syringe and needle handling practical 1 [PDF class handout]. LearnJCU. Updated February, 2014. Accessed March 2, 2014.


  • Most lecturers would rather you did not cite the lecture notes, but found the relevant information in books, journals or other such resources.  Only use lecture notes if you cannot find the information elsewhere.
  • Only include the full link to the document if a) you have tested the link and it will work several days after you originally accessed the document, and b) you are confident the person reading your work can access the site.  Otherwise, simply include the URL for LearnJCU.
  • If there is no attributed author, begin the reference with the title of the document.

Handouts given in class:

If the work was given in class, and you have confirmed that the information has not been copied from a published source (book, journal article, web page etc), treat it as personal communicationDo not include it in your reference list, and in text explain the nature of your source in brackets:


According to a diagram distributed by M. Grant (class handout, February 2015)...

The Cornell Method template (K. Bartlett, class handout, March 21, 2015) can be used to analyse and compare journal articles.


Class handouts are often copied or taken from other sources.  Endeavour to find the original source, if possible.

Note on URLs for LearnJCU:  Ideally, you use a URL that will get your readers as close as possible to the document.  When writing for someone who has access to the LearnJCU site, include the full URL for the document (copy and paste).  Always include the date you last checked to see the URL still worked (the Accessed date).

Multiple Authors - Rules

If there are six authors/editors or less, include the names of all authors/editors.

If there are more than six authors/editors, include the first three names, then shorten with et al.

These rules also apply to editors, translators and other people who need to be cited for the source.
