Citing sources has become streamlined (and easier!). A single concept applies across formats, with a set of core citation elements and source containers taking precedence.
What's an Element? The pieces of information that identify the source. The core elements of a citation can include : Author, Title of Source, Title of Container, Other contributor(s), Version, Number, Publisher, Publication Date, Location.
What are Containers? Containers are the element that holds the source. For example, a chapter is contained by a book, a video may be contained by YouTube, and a scholarly article is contained by a journal, which may be contained by an academic database.
