Source referencing provides the origin of information and processed texts, images and footage extracts used to create a published work.
Source references enable readers or viewers to assess the credibility of the information. They also give others the opportunity to improve or expand the information through further research. They also give the creator of the original work the validation they are entitled to. You must not present any words or ideas of others in your own document without mentioning the source, as this is considered plagiarism. When you use someone else's work, you have to reference the source under copyright law.
You can reference sources in several ways. Many universities of applied sciences and research universities use the APA Style.
