Before we learn how to reference a screenshot it is important to understand what is referencing and why do I need to provide references in any work, document, presentation, thesis, etc.
Simply, we use referencing to show anyone who reads our work that you understand the topic and can demonstrate your own thoughts on this. In order to demonstrate that you have read widely and deeply and then you will enable your reader to locate where you obtained each quote or idea.
When we reference a work we need to provide the original source as an acknowledge that you have read the work and recognise the original author and his ideas.
Referencing styles do differ from University to University. Harvard may have its own style but any paper or academic work may keep similar styles that readers around the world can understand. Harvard style of referencing is widely adopted and very popular also by academic honesty.
How do I provide references in my documents?
During the course of writing an essay or making a final presentation, report or other assignment it is usual to support arguments by referring to, or citing, information produced by other authors. This also applies for powerpoint .PPT presentations and other documents that are shared online or offline.
This information could be presented in journal or newspaper articles, government reports, books or specific chapters of books, research dissertations or theses, material over the internet etc. When you cite someone’s work in the text of your essay (an in-text citation), you also need to create a full reference for it at the end of your work. This gives the full details for the information source so that it can be traced by anyone who reads your work
How do I reference a printscreen of an image which I’ve obtaiend from a PDF or PPT presentation?
If you need to reference a screenshot, screen capture, or even diagrams or pictures in your slide, then you can use the same referencing rules.
To introduce the citation, you need mention something along the lines of “Referring to the diagram above…”, “the charts say…”, etc. On the other side, you can just mention at the end of the sentence, “Refer to the diagram above” in parentheses.
