ORCID ID: Similar to a DOI, the ORCID ID is a specific code that corresponds to a specific author/researcher. 

et al: Means "and others" in latin. This is sometimes used in citations when there are more than a certain number of authors.

Citation: A citation is a collection of information that tells your reader that certain material in your work came from another source. It also gives your reader all the information necessary to find the location of any source included in your reference list/bibliography/works cited.

APA: The list of citations at the end is called a Reference List.
