Books
One author
When there is one author of the book you are citing you can simply write the author’s last name and the year of publication in parenthesis. When the year of publication is not present just write n.d. in place of the year of the publication. (Author’s last name, Year) or (MacDonald, 2008). There is no need for page number in the in-text citation but page numbers will be required in the reference entry.
Multiple authors
When there are two authors you can write the last names of each of the authors separated by ampersand. For example (White & Miller, 2009).
In case there are three authors or as many as five, you need to write the last names of each of these authors in the first in-text citation. In each of the later in-text citation of the same work you will write the last name of the first author followed by et al. (First Author, Second Author, & Third Author, Year) or (Ahmad, Hassan, & Kamal, 2000).
Six or more than six authors you can cite the name of the first author followed by et al. For example (First Author, et al., Year) or (James et al., 1999).
No author
There might be no author mentioned on a book that you want to cite. If there is a corporate author you can mention the name of the corporate author like if it is any university publication you can mention the name of that. There might be a resource you want to cite that is published by a company or an organization, cite the name of that company, organization, or government department. For example (University of Colorado, 2000) or (Department of US Taxation, 1998).
Edited
The rules will remain the same as for citing any other book in the in-text the only difference will be that the name of the editor will replace the name of the author. If there is one editor or multiple editors follow the same rules that are for citing a book with one author or with multiple authors.
Online books
There is no difference between the in-text citation of online books and print books. The URL or DOI is not required in the in-text citation although you should provide it in the reference list. You have to provide the author name and the year of publication in the in-text citation. There should be a detailed entry for that online book in the reference list.
Journals

Multiple authors
List the last names of up to five authors in the in-text citation but not more than five. Journal articles have often a long list of authors involved so you can cite up to five authors. If there are more then five you can cite the last name of the first author and then write et al.
Online journal
