To format mixed sources in APA 7th edition, you treat primary and secondary sources identically in your reference list and in-text citations; there is no separate section for "Primary Sources" unless your professor specifically requested a split bibliography. For political science papers, the trick isn't a different category of citation, but using the correct template for the specific type of document. Peer-reviewed journals follow the standard author-date format, while government documents, legislative hearings, and statutes follow the Legal References style, which often incorporates elements from The Bluebook.
The Great Citation Misconception
Many students believe that because a source is a "primary source"—like a treaty, a piece of legislation, or a transcript of a congressional hearing—it requires a special label or a unique formatting style that separates it from "secondary sources" like academic journals. You might think you need to create two different bibliographies or add a note in the citation saying (Primary Source). This is a mistake.
This misconception usually happens because history departments often require separate lists for primary and secondary materials. But in Political Science using APA 7th, the focus is on the format of the medium, not the nature of the evidence. Whether you are citing a theory about power dynamics from a professor or the actual text of the Voting Rights Act, both go into one alphabetical list. The only thing that changes is the specific information you include in the reference entry to help the reader find that document.
Imagine you are a junior working on a paper about environmental policy. You have a peer-reviewed article from the American Political Science Review and a transcript from a Senate Committee hearing. If you try to treat the hearing as a "personal communication," you'll lose points. Personal communications are for things that cannot be recovered by the reader, like an email or a private interview. A legislative hearing is a public record. Treating a public document as a private one tells your professor you don't understand the difference between an archival record and a private conversation.
Handling the Heavy Hitters: Government and Legal Docs
The most stressful part of a 15-page paper is usually the government documents. These don't always have a clear "author" in the way a journal article does. In these cases, the government agency usually acts as the group author.
Legislative Hearings and Reports
If you are citing a hearing, don't panic about the lack of a traditional author. The committee is the author. You need the name of the committee, the date, the title of the hearing (usually in italics), and the publication information.
Example: U.S. House of Representatives, Committee on Foreign Affairs. (2021). The impact of sanctions on global trade (Hearing No. 117-12). Government Publishing Office.
If it is a report from an agency like the Department of State, the agency is the author. If the agency is also the publisher, you omit the publisher name at the end to avoid repetition.
Statutes and Bills
Laws are handled differently. You don't usually list a "person" as the author. Instead, you start with the name of the Act and the official source (like the U.S. Code).
For a bill that hasn't passed yet, you include the bill number and the legislative body. This is where students often get tripped up by trying to force a bill into a "report" format. A bill is a proposal; a report is a finding. Keep them distinct.
The Secondary Source Standard
Your peer-reviewed journals are the easy part, but they are where the most "sloppy" mistakes happen when you're rushing a deadline. Ensure you are using the DOI (Digital Object Identifier) for every journal article. If the article has a DOI, you must include it as a URL. If it doesn't, and you found it in a database, you don't need the database name—just end the citation after the page numbers.
A common mistake is including the "Retrieved from" phrase before a DOI. In APA 7th, that's gone. It's just the link. Also, make sure your journal titles are in italics and use title case, but the article titles use sentence case (only the first word and proper nouns are capitalized).
Decision Framework for Political Science Sources
Use this table when you aren't sure which "bucket" your source falls into. This will prevent you from mislabeling a public record as a personal communication.
| Source Type | Is it Recoverable? | APA Format Category | Key Detail to Include |
|---|---|---|---|
| Peer-Reviewed Journal | Yes | Periodical | DOI and Volume/Issue |
| Congressional Hearing | Yes | Government Document | Committee Name & Hearing No. |
| Executive Order | Yes | Legal Material | Order Number & Date |
| Email from a Senator | No | Personal Communication | In-text only (No Ref list) |
| Agency Report (PDF) | Yes | Report | Report Number (if available) |
Common Formatting Pitfalls
When you're staring at a 15-page draft at 2:00 AM, these are the errors that usually sneak in. Check your paper specifically for these three things:
- The "Author" Struggle: You might be tempted to put "United States Government" as the author for everything. Be more specific. Use "U.S. Department of Justice" or "Senate Committee on Finance." The more specific the agency, the better.
- The In-Text Mismatch: Ensure the first word of your in-text citation matches the first word of your reference list entry. If your reference starts with "U.S. House of Representatives," your in-text citation must be (U.S. House of Representatives, 2021), not (House of Representatives, 2021).
- Over-italicizing: Only italicize the "container" (the journal name, the book title, or the report title). Do not italicize the title of the specific article within the journal.
Putting it Together: A Practical Scenario
Let's say you're writing about the legislative process of a specific healthcare bill. You have three sources: a journal article analyzing the bill, the text of the bill itself, and an email from a legislative aide who gave you background info.
- The Journal Article: This goes in your reference list. Format: Author, A. A. (Year). Title of article. Journal Name, Vol(Issue), pages. DOI
- The Bill: This goes in your reference list. Format: Name of Bill, Bill Number, Legislative Body (Year).
- The Email: This does not go in your reference list. Because the reader cannot go to a library and find that email, it is a personal communication. You only cite it in the text: (J. Doe, personal communication, October 12, 2023).
By separating these correctly, you show your professor that you understand the hierarchy of evidence. You aren't just "citing things"; you are identifying the legal and academic weight of your sources.
The single most important truth to remember is that APA 7th cares about how the reader finds the source, not whether the source is a primary or secondary piece of evidence. If it's a public document, it gets a full reference; if it's a private conversation, it's in-text only.
