When citing a book in your research paper, you must cite the page numbers and number of authors in the reference. Page numbers for a book are in parentheses; however, page numbers in a periodical reference do not need this prefix. Edition numbers should be listed in the same parentheses as page numbers and separated by a comma. The following tips will help you format your reference properly.

In-text citations

In-text citations in the 7th edition of the APA style are used to reference sources within the text of your paper. When citing a website, a page number is not required. However, if the webpage does not have a page number, you can cite it by using the title, author, and publication year. To avoid errors, the author and publication year of an unknown source should also be noted within the citation.

Citation style in the 7th edition of the APA requires in-text citations to be accurate and properly reference the source. These citations point to the relevant source in the references page. If a source is a direct quote, it is important to include the page number and author’s last name as well as the year of the article. For secondary sources, an in-text citation is not needed if it is merely a brief summary of the main findings.

Number of authors

If a work has more than one author, the APA recommends listing all authors, up to 20. For works that have more than 20 authors, the first name and surname should be listed together in the reference list. If there are more than 20 authors, use ellipsis (-) to separate the first 19 names. To follow the APA format, list all authors’ surnames and initials after the first author’s last name.

If there are more than 20 authors, list the first nineteen before using ellipses. In this case, it would be a proper practice to use ellipses to separate the names. The last author’s name would be listed after the ellipsis. In either case, there should not be more than twenty authors listed in a source. However, if a source has more than 20 authors, use ellipses to separate each author’s last name.

Capitalization

APA style cites books and periodicals using a title in italics, but titles of books should be capitalized. Depending on whether you’re citing a book or journal, you may also need to include the publisher’s name. To know how to capitalize a book, see section 10.2 of the APA publication manual. This section outlines the guidelines for citing books and journal articles.

In APA style, titles should be capitalized, and proper names in the title should be capitalized. However, if you’re citing a book or journal, you may want to use sentence case when using proper nouns. If the title is a book or journal, capitalize the first word and any sub-title. Also, use sentence case for titles of articles, short works, and periodicals that don’t begin with an article or a colon.

Identifying a specific passage

APA 7th edition has changed how references are made in-text. Now, APA references must include the author’s surname and year of publication in the body of text. Then, the author’s name should be included in brackets, along with a paragraph number, which can be either a paragraph or page number. However, if the author doesn’t use a page number, the author must include a paragraph or chapter title in order to locate the passage.
