There are several ways to add citations in your essay. These include the in-text citation, bibliography, APA style, and Chicago style. You should also know the differences between the two types of citations. Here are some tips to use properly:
Author Date style
Chicago author-date style citations refer to books. The author’s name and the date of publication should appear in parentheses after the title. Depending on your source, you may include a locator-reference (page, paragraph, or section number) in the parenthetical citation. This style applies to all types of books, including translated works and electronic documents. You should also include the city of publication and any other information relevant to the source.

The author-date style citation system is recommended by the APA. Authors’ last names and dates are given after the title in the reference list. All in-text citations must include the surname of the first author, as well as the first and last name. In all citations, you should also include “et al.” whenever there is ambiguity about the authorship of the source.
APA style
APA style requires citations to be in the proper order. Its first step is to format the reference page. The reference page should have a title page and a running head (a shortened version of the paper’s title). The title page should contain no more than 50 characters, including spaces. This page should also include the author’s last name and first initial. After the running head, the text should be centered and spaced correctly. Then, follow the format described in the APA manual, which is the most common format.
In APA style, you must use the past tense when citing a source. The present tense must not be used when citing a source. Using the past tense means that you are citing the research done by Brooks in 1972a. You must also make sure to include the date the research was conducted. APA style also requires you to use the correct verb tense in a sentence.
Chicago style
If you’re writing an essay, you’re probably going to need to cite some sources in Chicago Style. This style of citation is most common among students studying Social Sciences. However, you’ll have to make sure you follow the formatting rules, including the spacing, font size, and indentations. The following are some important tips to help you make the most of this style of citation. Read on to learn more.
The Chicago citation system has two types of citations. Short and full notes are used in an essay. The former contains full publication details, while the latter merely includes the author’s last name, title, and page number. You should use the former for the first time, while the latter is used when citing a source more than once. In Chicago style, you should assign a number to your source, unless you want to repeat it in the bibliography.
Vancouver style
When using the Vancouver style for adding citations to an academic essay, it is important to follow specific formatting rules. Vancouver style does not allow direct quotations, but quotations placed in parenthesis should be accompanied by the page and citation numbers. Citations can be in the form of ellipses or full sentences, as long as they do not appear in the body of the essay. However, if they are too long, they should be presented in full sentences.
In the Vancouver style, the references are listed in order of first appearance in the text. Generally, references appear in a numerical order, starting with the first citation in the text. The numbers are placed after the title and the date. Vancouver referencing requires a comma or full stop after each entry. You can also use a URL or DOI as the last element. Remember to keep references in plain text and avoid quotation marks and italics.
