Identifying Different Types of Sources/Introduction

From UBC Wiki

Choosing suitable sources for any piece of scientific writing – especially a scholarly one, such as a lab report or essay – is extremely important. This is because these sources will help add relevant detail to your writing, provide more information for interested readers, and allow you to share evidence that supports the argument you are developing. The credibility of your writing will directly relate to the quality of the sources you cite, which is why it is so important that you are able to identify the different types before you cite them (primary, secondary and tertiary).
