Answer: Books, journals, Web sites, periodicals, etc. are used and known as the sources listed in a bibliography.
Explanation:
A bibliography is a list of sources - books, journals, Web sites, periodicals, etc., that we use during the research process, when writing a research paper or similar work. Depending on the style format we use (MLA, Chicago, APA, etc.), bibliography is also referred to as 'References' or 'Works Cited'. It usually appears on the last page of a paper. A bibliography typically includes the following bibliographic information - the authors' names, book (or other source) title, the information about the publishing company (name, location), pages cited, etc.
