What is a secondary source?
Secondary sources are sources which describe an event, but did not originate in the time period they describe. They were created by someone based on firsthand accounts. They are the second time the event has been described or depicted. Generally speaking, they are books or scholarly articles.
How do I know if my material is a secondary source?
If your point of reference is a book, an article, or an overview of an event, the chances are that it is a secondary source. These texts will have a bibliography and a list of references. This bibliography will include the works that inspired the research, or were quoted within the text itself. Examples of secondary sources are:
- A book
- An article
- An overview of an event written by someone who did not witness the event
- A review of a book/piece of art
- A commentary
- An encyclopaedia
How do I find secondary sources?
Secondary sources are a lot easier to come by than primary ones. Secondary sources will help you find introductory information about your research. Encyclopaedia entries are secondary sources, so too are commentaries, reviews, and criticisms.
Any material which summarizes research undertaken by someone else is a secondary source. A project you complete, if consulted by someone else and used in their research, is a secondary source.
Why do I need secondary sources?
Secondary sources will provide you with different ideas and standpoints about the subject you are researching. Each text will have its own bias and will look at the subject from a different angle, so by reading secondary sources you are engaging with multiple interpretations of the same event.
This broad reading gives you a solid foundation to analyse the event/text/object while acknowledging the bias and outlook of research professionals. By engaging in the reading of secondary sources you are also backing up your arguments with the support of well-known experts in the field. Without reading secondary sources you cannot be sure if your argument is valid, or if you are plagiarizing.
Do I need to cite secondary sources?
Yes! Without a shadow of a doubt, yes. Secondary sources are written by people who are arguing for or against the point you are making. You need to reference where you got your idea, your quotes, everything. If you are paraphrasing, you need to reference where from.
If you do not cite your secondary sources, you are plagiarizing. Plagiarism is completely unacceptable. It is an act of fraud because you are stealing someone else’s idea and pretending it is yours. In some countries, plagiarism is illegal if/when it violates copyright.
How you cite your secondary sources depends on the requirements of your publication/university, but what is important is that you make sure you cite everything correctly. This includes not only the author and title of the text, but also the issue or edition of the book/article, the page number, publisher, and in the case of websites, the date you accessed the information.
You’ll find more information about citation requirements in the style guide of the system you are required to use.
