Final answer:
The correct option is c) Periodicals.
Periodicals are publications that are issued at regular intervals and include journals, magazines, and newspapers. They can be accessed through databases and are available in print and online, commonly behind a paywall. Many periodicals, especially academic journals, are peer-reviewed to ensure high-quality content.
Step-by-step explanation:
Publications that come out "periodically" such as journals, magazines, and newspapers are known as periodicals. These include articles, reviews, editorials, and other short works that can be found in both print and electronic forms.
Students often access these through databases provided by their library, which may include a variety of works from peer-reviewed academic publications to general-interest pieces. Academic peer-reviewed articles, in particular, are part of the gold standard in research, as they undergo a rigorous evaluation process by other experts in the field before publication.
A basic format for citing an article from an academic journal within a database would look like this: Author's Last Name, First Name. "Title of Article." Title of Journal, volume number, issue number, Date of Publication, page numbers. Title of Database, DOI or URL.
