Hi, this is a very broad question. But there are two main ways you need to cite your sources: in-text citations and bibliography citations. I will be going by the APA 7th edition because that is the most recent version, but it is important to check to see which kind of APA your teacher wants.
In-text citations
For in-text citations, you always need to include the author's last name and the date the material was written. For example, if the author's last name is Smith and the book you are using as a source was written in 2012, the citation would be (Smith, 2012). You put this citation at the end of the information you are using from that book. If you are paraphrasing, that is all the in-text citations you need. But, if you are directly quoting, you also need to add the page number/numbers at the end of the citation. So if you are pulling a quote from page 21, the citation would look like (Smith, 2012, p. 21). If you are pulling a quote from a range multiple pages (for example 21-22), it might look like (Smith, 2012, pp. 21-22). Always use p. for one page, pp. for multiple.
Reference list citations
Every in-text citation needs a bibliographical citation, also known as a reference list. This is the list of sources at the end of the paper. Bibliographies are typically in alphabetical order by the first part of the citation. This citation depends on what kind of material the source is. There are many different types of materials. For example: books, journals, newspapers, movies, etc. Nowadays, most people do not memorize the specific order for each citation type. It's a lot easier to simply look up "how to cite _____ in APA" and plug in the material type.
For example, to cite a book, you need to include:
Last name, Initials. (Year). Book title (Editor/translator initials, Last name, Ed. or Trans.) (Edition). Publisher.
To cite a journal article, you need to include:
Author’s Last Name, Initial(s). (Year of publication). Title of article. Title of Journal, Volume(Issue), Pages. https://doi.org/DOI
Some good things to remember for the reference list:
- You indent every line besides the first line in each citation. For example:
- Fraga, K. (2021, October 18). Dolores Huerta has fought for civil rights for over 60
years-despite nearly being killed for it. All That's Interesting. Retrieved October 19, 2021
- Italicize titles of journals, magazines, newspapers, and books
- Some teachers/professors don't care if you include the doi for journal articles and website links for webpages. But always make sure to ask before you get rid of it
You can find citation machines online that are fairly accurate. Also, if you find a source through university libraries, there is usually the choice for the portal to create citations for you. Just be aware that these aren't always accurate 100% of the time. Purdue owl has really good breakdowns of all of the citation rules for APA for each different source, if you want to make the citations manually. Here is the link for that:
