You may include more than the author's last name and page number when providing a direct quotation that does not fit within the main body of your text and needs to be highlighted or if you are citing from a source without page numbers, like a website, where additional information is needed to locate the specific section of the source.
When a reference has more than six authors, in APA style, you can include the first six authors followed by ellipses (...) and then the last author's name.
In APA, you would include the first and middle initials of each author in order to distinguish between them. See this page for an example (under the heading "If two authors have the same last name"): http://leo.stcloudstate.edu/research/apaintext.html In MLA, you would include the authors' first names. See this site for an example: http://leo.stcloudstate.edu/research/mlaparen.html
In MLA style, in-text citations that include the last name of the author or authors and the page number are called parenthetical citations. These citations help readers locate the complete source information in the works cited list at the end of the document.
You can differentiate authors with the same last name and first initial by including their full first name in the citation. If both authors have the same first name as well, you can include their middle initial. If that is also the same, you can list their names in the order they appear in the original work.
Some authors whose last name begins with the letter B include J.D. Salinger, Ray Bradbury, Emily Brontë, and Charlotte Brontë.
In MLA style, you would list multiple authors by separating their names with a comma and the word "and" before the last author's name. For example: Last name, First name of Author 1, and First name Last name of Author 2.
In APA formatting style the citations should include the author's last name. But if the author's name is mentioned within the text, it is no longer necessary to include it within the citation.
In MLA style, an author-page style parenthetical citation should include the author's last name and the page number(s) from the source. A parenthetical citation for a print source (books, magazines, scholarly journal articles, newspapers) with a known author should include a signal word or phrase (usually the author's last name) and a page number. A parenthetical citation for print source with no known author should include a shortened title of the work and a page number. Other things that may need to be included in a parenthetical citation include information about the edition of the source, a first initial if authors have the same last name, the volume number if citing from different volumes of a multi-volume work, and, when citing the Bible, the version you are using along with book, chapter, and verse.
The last whole number before 1890 is 1889. There is no answer if you include decimal values.
When citing a quote with two authors in APA format, include both authors' last names in the in-text citation, separated by an ampersand (&). For example: (Author1 & Author2, Year). In the reference list, list both authors' last names followed by a comma and an ampersand before the final author's name.
("Last Name" and "Last Name," Page Number) There are no quotation marks or commas in the citation.
When citing different authors with the same last name, include enough information so as to be able to differentiate them: e.g., (M. Oolaf 48); (R. Oolaf 36)
