What is citation?
When writing, if you are referring to information that is directly attributable to another source it is often expected that you identify where this information came from. For example, if I wrote, “Francis Scott developed a new form of measuring temperature.”, I should acknowledge where I got this information from by making some type of notation directly after the statement. This is known as citation or in-text citation. In-text citation is usually written immediately after the citable text by inserting the author(s) surname(s) and publication date in brackets. This is known as the Author-Date System. Another common form is the Number System where a superscript number is written directly after the citable text. In both types, the full details of the source of the citation is compiled as a list of references at the end of the document. The number system is commonly used in all Wikipedia articles where hyperlinking is also commonly used to refer to sources.
Should everyone use citation?
No. Whether you cite the source of your information depends on the type of document you are writing and what discipline you are writing for. In-text citations are expected in academic and peer-reviewed research publications and in many scientific reports and other technical publications. If you are writing an industry, client, government or commercially-sensitive report, first check whether you are expected to cite. For scientific blogposts and other online documents, hyperlinking your sources may be sufficient but be mindful that these links should be regularly checked to ensure they are still working.
What citation style should I use?
There are a wide variety of referencing styles stipulating how to record an in-text citation and how to compile a bibliography or list of references. The most common types for the sciences are either Harvard or APA (American Psychological Association) which are both an Author-Date system. What style you choose may depend upon your document type, publisher, discipline or organisation. If working within a research institution or university, check with your library, department or supervisor about what style you should use. However, depending upon the circumstances there is often individual choice.
