Answer:
Title, URL/Web Address, Publisher, Author.
Step-by-step explanation:
Citing or providing citations to academic or literary writing is the act of giving the list of important details about the book or sources from which the writer takes help while writing the paper. This means that the citation consists of the important details about any source used while writing the paper.
For research, citations are a must to make sure that the paper written is produced according to the legal rules of any literary writing. This means that the writer of the research paper has to provide the list of books or sources that he/she used to refer to while working on the paper.
So, the information needed while citing requires the name of the author, the publisher, the title of the book/source, and the URL address if it is accessed online.
