Being Responsible While Researching

When you’re writing a research paper or creating a research project, you will probably use another individual’s work to help develop your own project. A good researcher or scholar uses another individual’s work in a responsible way. This involves indicating that the work of other individuals is included in your project, which is one way to prevent plagiarism.

Plagiarism? What is it?

The word plagiarism is derived from the latin word, plagiare, which means to kidnap. The term has evolved over the years to now mean the act of taking another individual’s work and using it as your own, without acknowledging the original author. Be careful of plagiarism! Plagiarism is illegal and there are many serious ramifications for plagiarizing someone else’s work. Thankfully, plagiarism can be prevented. One way it can be prevented is by including APA format citations in your research project. Want to make these citations quickly and easily? Try our APA citation machine which is found on our homepage.

All about Citations:

Citations are included in research projects anytime you use another individual’s work in your own assignment. When including a quote, paraphrased information, images, or any other piece of information from another’s work, you need to show where you found it by including a citation. This APA format guide explains how to make citations in APA style.

There are two types of APA citations. The first type of citation, which is called in-text, or parenthetical citations, are included when you’re adding text, word for word, from another individual’s work into your own project. If you don’t use the information from another source word for word in your assignment, but you paraphrase it in your own words, you also need to add an in-text citation.

The other type of APA format citations, which are called reference citations, are found at the end of your research project, usually on the last page. Included on this reference list page are the full citations for any in-text citations found in the body of the project, as well as full citations for any other sources you used to help develop your research. These citations are listed in alphabetical order, one after the other.

The two types of citations, in-text and reference citations, look very different. In-text citations include three items: the last name(s) of the author, the year the source was published, and the page or location of the information. Reference citations include more information such as the name of the author(s), the year the source was published, the title of the source, and the URL or page range.

Why is it Important to Include APA Citations?

Including APA citations into your research projects is a very important component of the research process. When you include citations, you’re being a responsible researcher. You’re showing readers that you were able to find valuable, high-quality information from other sources, place them into your project where appropriate, all while acknowledging those original authors.

Information About APA

Who Created APA?

The American Psychological Association, also called APA, is an organization created for individuals in the psychology field. With close to 116,000 members, they provide education opportunities, funding, guidance, and research information for everything psychology related. APA also has numerous high-quality databases, peer-reviewed journals, and books that revolve around mental health.

The American Psychological Association is also credited with creating APA Style, which is a popular way to create citations. This citation format is used by individuals not only in the psychology field, but many other subject areas as well. Education, economics, business, and social sciences also use APA style quite frequently. Click here for more information.

Why Was APA Style Created?

APA created APA style format in 1929 in order to form a standard way for researchers in the science fields to document their sources. Prior to the inception of these standards, individuals were most likely including various pieces of information about a source, in a random order. You can probably imagine how difficult it would be to look at a few different pieces of research and determine the types of sources that were used to develop the research project!

Having a standard format for citing sources allows readers to glance at an APA citation and easily locate the title, author, year published, and other critical pieces of information needed to understand a source.

The Evolution of APA Style:

APA Style is currently in its 6th edition, which was released in 2009. In previous versions of APA format, researchers and scholars were required to include the date that an electronic resource was accessed. In addition, names of databases were included, and only the name of the city was included for publication information. Now, it is no longer required to include the date of access as well as the name of the database in an APA citation. The full location, including the city AND state, or the city and country if it’s an international publisher, is included in the citation.

In 2013, APA released a revised manual just for electronic resources. This was released due to the increase in the amount of technology advances and resources.

APA Style and Citations

The Appearance of APA Citations:

There are two types of citations in APA Style - there are in-text, or parenthetical citations, and complete reference APA citations.

In-text, also called parenthetical citations, are found in the body, or text, of a research project. They’re included after a direct quote or paraphrase. See the next section below to learn more about how to format and include in-text citations in your project.

Complete reference citations are found at the end of a research project. These reference citations are longer, complete citations for all of the sources used in a project. So, full citations for all of the in-text citations are found here.

The format for APA reference citations varies, but some APA citations use this general format:

Author’s Last name, First initial. (Date published). Title. Retrieved from URL

Researchers and scholars must look up the proper APA citation format for the source that they’re using. Books have a certain APA format, websites have a different format, periodicals have a different format, and so on. Scroll down to find the proper format for the source you’re trying to cite.

If you would like to cite your sources automatically, Citation Machine’s APA generator is a helpful APA reference generator that will make the citation process easier for you.

In Text & Parenthetical Citations:

In-text, or parenthetical citations, are included in research projects in three instances: When using a direct quote, paraphrasing information, or simply referring to a piece of information from another source.

Quite often, researchers and scholars use a small amount of text, word for word, from another source and include it in their own research projects. This is done for many reasons. Sometimes, another author’s words are so eloquently written that there isn’t a better way to rephrase it yourself. Other times, the author’s words can help prove a point or establish an understanding for something in your research project. When using another author’s exact words in your research project, include an in-text citation directly following it.

In addition to using the exact words from another source and placing them into your project, in-text citations are also added anytime you paraphrase information. Paraphrasing is when you take information from another source and rephrase it, in your own words.

When simply referring to another piece of information from another source, also include an in-text citation directly following it.

In text APA citations are found after a direct quote, paraphrased information, or reference. They are formatted like this:

Exact text, paraphrased information, or reference (Author’s Last Name, Year published, page number or paragraph number*)

*Only include the page or paragraph number when using a direct quote or paraphrase. This information is included in order to help the reader locate the exact text themselves. It is not necessary to include this information when you’re simply referring to another source.

Here’s are some examples of in-text APA citations:

“Well, you’re about to enter the land of the free and the brave. And I don’t know how you got that stamp on your passport. The priest must know someone” (Tóibín, 2009, p. 52).

Student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers (Kent & Giles, 2017).

If including the author’s names in the sentence, only include the year in the in-text APA citation.

Example:

According to a study done by Kent and Giles (2017), student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers.

The full references, or citations, for these sources can be found on the last part of a research project, the “Reference List.”

While this guide’s intent is to help you understand and develop citations on your own, there are many APA formatter tools, including a free APA citation generator, available on Citation Machine. Try our APA citation machine which is found on our homepage.

APA Reference List Citation Components

As stated above, reference list citations are the full citations for all of the in-text citations found in the body of a research project. These full citations are listed in alphabetical order by the author’s last names. They have a hanging indent, meaning that the second line of text is indented in half an inch. See examples below to see what a hanging indent looks like.

The format for APA reference citations varies based on the source type, but some APA citations use this general format:

Author’s Last name, First initial. (Date published). Title. Retrieved from URL

Learn more about each component of the reference citation and how to format it in the sections that follow.

Author’s Names

The names of authors are written in reverse order. Include the initials for the first and middle names. End this information with a period.

Last name, F. M.

Angelou, M.
Doyle, A. C.

Two or more authors

When two or more authors work together on a source, write them in the order in which they appear on the source, using this format:

Last name, F. M., Last name, F. M., Last name, F. M., Last name, F. M., & Last name, F. M.

Kent, A. G., & Giles, R. M.
Thorpe, A., Lukes, R., Bever, D. J, & He, Y.

If there are 8 or more authors listed on a source, only include the first 6 authors, add three ellipses, and then add the last author’s name.

Roberts, A., Johnson, M. C., Klein, J., Cheng, E. V., Sherman, A., Levin, K. K. , ...Lopez, G. S.

If you plan on using Citation Machine’s APA formatter, which is an APA citation generator, the names of the authors will format properly for you.

Publication Information

Directly after the author’s name is the date the source was published. Include the full date for newspapers, the month and year for magazine articles, and only the year for journals and all other sources. If no date is found on the source, include the initials, n.d. for “no date.”

Newspaper:

Narducci, M. (2017, May 19). City renames part of 11th Street Ed Snider Way to honor Flyers founder. The Philadelphia Inquirer.

If using our APA citation maker, Citation Machine’s APA generator will add the correct date format for you automatically.

Titles

When writing out titles for books, articles, chapters, or other nonperiodical sources, only capitalize the first word of the title and the first word of the subtitle. Names of people, places, organizations, and other proper nouns also have the first letter capitalized.

For books and reports, italicize the title in an APA citation.

Examples:

Strange case of Dr. Jekyll and Mr. Hyde.
Roots: The saga of an American family.

For articles and chapters in APA referencing, do not italicize the title.

Examples:

Wake up the nation: Public libraries, policy making, and political discourse.

For newspapers, magazines, journals, newsletters, and other periodicals, capitalize the first letter in each word and italicize the title.

Example:

The Seattle Times.

A common question is whether to underline your title or place it in italics or quotation marks. In APA, titles are never underlined or placed in quotation marks. They are either placed in italics or not. Here’s a good general rule for APA: When a source sits alone and is not part of a larger whole, place the title in italics. If the source does not sit alone and is part of a larger whole, do not place it in italics.

Books, movies, journals, and television shows are placed in italics since they stand alone.
Songs on an album, episodes of television shows, chapters in books, and articles in journals are not placed in italics since they are smaller pieces of larger wholes.

Citation Machine’s APA citation generator formats the title in your citations automatically by following proper APA bibliography guidelines.

Additional Information about the Title

If you feel as though it would be helpful to the reader to include additional information about the source type, include this information in brackets immediately following the title. Use a brief descriptive term and capitalize the first letter.

Example:

Kennedy, K., & Molen, G. R. (Producer), & Spielberg, S. (Director). (1993). Jurassic Park [Motion picture]. USA: Universal.

Besides [Motion picture], other common notations include:

[Audio podcast]
[Brochure]
[Letter to the editor]
[Television series episode]
[Tweet]
[Facebook page]
[Blog post]
[Lecture notes]
[PowerPoint presentation]
[Video file]

If you are using Citation Machine’s APA formatter, additional information about the title is automatically added for you. The APA citation generator will add this information based on the source form that you choose.

Information About the Publication

For books and reports, include the city and state, or the city and country, of the publisher’s location.

  • Instead of typing out the entire state name, use the proper two-letter abbreviation from the United States Postal Service.
  • Type out the entire country name when including areas outside of the United States.

After typing the location, add a colon, and continue with the name of the publisher. It is not necessary to include the entire name of the publisher. It is acceptable to use a brief, intelligible form. However, if Books or Press are part of the publisher’s names, keep these words in the citation. Other common terms, such as Inc., Co., Publishers, and others can be omitted.

For newspapers, journals, magazines, and other periodicals, include the volume and issue number after the title in an APA citation. The volume number is listed first, by itself, in italics. The issue number is in parentheses immediately after it, not italicized.

Example:

Giannoukos, G., Besas, G., Hictour, V., & Georgas, T. (2016, May). A study on the role of computers in adult education. Educational Research and Reviews, 11(9), 907-923. Retrieved from http://dx.doi.org/10.5897/ERR2016.2688

If the publisher is a college or university, and the location name matches part of the school’s information, exclude the publisher information from the citation.

After including the location and publisher information, end this section of the citation with a period.

Examples:

London, England: Pearson.
New York, NY: Perseus Books.

Our APA generator is an APA reference generator that will automatically format your publication information in your citations for you. Visit Citation Machine’s homepage to learn more.

Electronic Source Information:

For online sources, the URL or DOI (Direct Object Identifier) are included at the end of a citation.

DOI numbers are often created by publishers for journal articles and other periodical sources. They were created in response to the problem of broken or outdated links and URLs. When a journal article is assigned a DOI number, it is static, and will never change. Because of its permanent characteristic, DOIs are the preferred type of electronic information to include in APA citations. When a DOI number is not available, include the source’s URL.

For DOIs, include the number in this format:

http://dx.doi.org/xxxxx

For URLs, only include the information about the homepage and write it in this format:

Retrieved from http://

Other APA referencing information about electronic sources:

  • - If the URL is longer than a line, break it up before a punctuation mark.
  • - Do not place a period at the end of the citation.
  • - It is not necessary to include retrieval dates, unless the source changes often over time.
  • - It is not necessary to include the names of databases

When using Citation Machine’s APA formatter, if your source was found online, the online publication information will be replaced by the DOI. Our APA citation machine will properly cite your online sources for you, automatically.
