How many sources do you need in a literature review?

February 19, 2014

Students often ask me how many sources they need in their literature review. The short answer is, “It depends.” It depends on your topic, the nature of your research project, your level of scholarship, and a number of other factors.

An article from Canberra University (http://www.canberra.edu.au/studyskills/writing/literature) suggests:

  • Undergraduate review: 5-20 titles depending on level
  • Honours dissertation: 20+ titles
  • Master’s thesis: 40+ titles
  • Doctoral thesis: 50+ titles

Another strategy I learned somewhere along the way that I now share with my students is this:

If your literature review is one section of a larger research paper, thesis or dissertation

 Minimum number of sources = number of pages in the body of your entire paper (exclusive of title page, abstract, appendices and references)

Example: A paper that has 10 pages of content (the body of the paper) needs at least 10 sources in its literature review. 

A thesis of 100 pages (in the body) includes at least 100 sources.

If your literature review is a stand-alone document

Minimum number of sources =  3 times the number of pages in the body of your paper (exclusive of title page, abstract, appendices and references)

Example: A stand-alone literature review that has 10 pages of content (the body of the paper) should examine at least 30 sources.

These are not hard and fast rules by any means. Also, it is worth mentioning that as students and scholars who care about the quality of our work, we want to aim to raise the bar, not simply meet a minimum suggested standard. What these guidelines are suggesting is that you don’t aim for any less. If you do, your search for relevant literature in your field may be incomplete and you need to keep digging. Of course, your sources have to be relevant to your topic, too.

Not every scholar or academic supervisor would agree with the guidelines I offer here, criticizing them as being too reductionist or simplistic. My point isn’t to offer a black and white rule or open theoretical debate for which there can be no clear solution, but rather to offer a straight forward and practical answer to a question that academics often respond to in an ambiguous way, leaving students frustrated, exasperated and anxious about how to go conduct their literature review. 

When in doubt, talk with your own instructor or supervisor, asking them what their expectations are. (Don’t be surprised though, if you get an answer that is vague, like, “It depends…”)

Remember: Aim for quality over quality… and to do a quality literature review, you need to have a substantive quantity of sources.

What’s the difference between a citation and a reference?

October 18, 2013

Sarah Eaton blog technology researchThere are certain things no one tells you (usually) when you are a university student. You are just expected to know them. When you learn them, suddenly it is as if you are part of an inner circle of respected peers who accept you… but you are not really sure how you got there. The devil is in the details. What sets rookies apart from experts is deep knowledge of details and sublties that others overlook or gloss over. Knowing the difference between a citation and a reference is one of those subtle details that moves you from the category of “novice researcher” to “respected researcher”.

It’s one of those things that you don’t really need to know — until you really want to be taken seriously among a group of experts. It’s akin to car buffs who know the difference between a supercharger and a turbocharger. Unless you are a “gear head” you don’t need to know. But if you want to be taken seriously in that social circle, you might be shunned if you didn’t know.

Regardless of your field, one key element that sets the experts apart from everyone else is their understanding of details in various elements of our work.

For students and scholars, once of these subtleties is knowing the difference between a citation and a reference:

Citation

A specific source that you mention in the body of your paper. The format of the citation may change depending on the style you use (e.g. MLA and APA) and the way that you weave the citation into your writing, but the basic elements of the citation that you need to include are:

  •  Name of the author(s)
  • Year of publication
  • Page number or page range

If you quote a source directly you must include the exact page number in your citation or it is incomplete.

References

This is a list of the the sources you have cited. The references come at the end of your paper. In APA style, this is not a list of “works consulted”. Every source that is listed in your references also needs to be cited in the body of your paper.

Every source listed in your references should be accessible by others who read your work. Think of it as a trail of breadcrumbs that you leave for readers to show them where they can go to find the original source material for themselves.

In APA style, not all work that is cited necessarily goes into the references. For example, personal communications get cited in the body of your paper, to show the reader that you have a source for your information. But if the reader can not track that source as a primary document (because, for example, the information is contained within a private e-mail between you and someone else), then it does not go into the reference list.

Alert! It is not very common that sources are cited but not referenced. Use sources such as personal communications sparingly, if at all. The more credible sources you have in your references, the better quality your work will be perceived as having.

In general, there should be an exact match between the sources you cite in the body of your paper and those that appear in your references.

The actual books, articles and other materials you consult are called your sources of information. You need to know how to cite and reference all your sources correctly.

Now you know one of the subtle differences of of terms used in scholarship that sets apart the experts from the rookies. When you use the terms correctly, those who know will quietly nod their head and accept you a member of the scholarly community.
