Scientific knowledge evolves thanks to the contributions of many different scientists (VandenBos, 2010). Therefore, every scientific work needs to be placed into context in order to show how it refers to theories in the field and findings of earlier work. Correct citations document the impact of a given work on scientific theory and show how the work further extends previous results. This presentation helps to understand when citations are needed.

It is important to credit the work of other researchers that you draw on in your own inquiry. By doing so, you avoid plagiarism. Examine the following issues that are further explored in the video:

Question: When do I need a citation?
Answer: Whenever a statement is not self-evident.

Question: How often can I use ‘direct quotes’ in my text?
Answer: As rarely as possible, as often as absolutely necessary. Reformulate in your own words – use direct quotes only for definitions.

Question: When do I need multiple citations? Answer: With general statements, multiple topics, and topics investigated by many studies.
