Thesis Chapter 1 Citation Examples
Your bibliography
0 sourcesThesis Chapter 1 Citation Examples show how to cite the books, journal articles, and prior studies you reference in your introduction. Chapter 1 uses the same in-text and reference formatting as the rest of the thesis: choose APA, MLA, or Chicago and apply it consistently.
What gets cited in a thesis Chapter 1?
Chapter 1 (the Introduction) cites the sources that establish your problem, background, and rationale. You typically cite foundational theories, key statistics, seminal studies, and the gap your research addresses. Every claim borrowed from another author needs an in-text citation and a matching reference-list entry.
Chapter 1 does not use a different citation format from the rest of the thesis. The style your department or journal requires — APA, MLA, or Chicago — applies uniformly across all chapters. What changes is what you cite: introductions lean on context-setting sources rather than exhaustive method-level references.
Chapter 1 in-text citation examples
In-text citations appear inside your introduction sentences and point to a full reference at the end. APA uses author–date, MLA uses author–page, and Chicago notes style uses superscript footnote numbers. Below are the three most common patterns you will write in Chapter 1.
| Style | Parenthetical | Narrative |
|---|---|---|
| APA 7 | (Creswell & Creswell, 2018) | Creswell and Creswell (2018) argue that… |
| MLA 9 | (Creswell and Creswell 12) | Creswell and Creswell note that… (12). |
| Chicago (notes) | …mixed methods design.1 | Creswell and Creswell describe…1 |

The anatomy of a Chapter 1 reference
Most Chapter 1 references are journal articles or books. The APA journal reference below shows the five elements every full citation contains — learn these once and every style becomes a rearrangement of the same parts.
- Author — surname then initials, inverted, joined with an ampersand
- Date — publication year in parentheses
- Title — article title in sentence case, not italicised
- Source — italic journal name, volume, issue, page range
- DOI — full https link, no period after
APA Chapter 1 reference examples
APA 7 is the dominant style for education, psychology, nursing, and social-science theses. References sit in an alphabetised list with a hanging indent. Here are the source types you will most often cite in an APA introduction.

MLA Chapter 1 works-cited examples
MLA 9 is standard for humanities theses in literature, languages, and cultural studies. Entries go in a “Works Cited” list, author names are given in full, and titles use title case. In-text citations pair the author with a page number.

Chicago Chapter 1 citation examples
Chicago 18 appears in history, theology, and some social-science theses. Its notes-and-bibliography system uses a numbered footnote at first mention plus a bibliography entry. The footnote includes the specific page you drew from; the bibliography does not.

Citing a thesis or dissertation itself
Chapter 1 often cites earlier theses to show the research gap. How you cite one depends on whether it was retrieved from a database or held unpublished at a university. The examples below cover both cases across the three styles.

How accurate are these examples — and their limits
These templates follow the official APA 7th, MLA 9th, and Chicago 18th edition manuals and are correct for standard book, journal, chapter, and thesis sources. They cover the sources that make up the large majority of Chapter 1 citations. They are patterns, not one-size-fits-all rules.
Edge cases still need judgement. Sources with no author, missing dates, corporate authors, multiple works by one author in the same year, or non-English titles follow additional rules not shown here. Many universities also publish a house style guide that overrides the standard manual on formatting details such as spacing, heading levels, and the placement of the reference list. Always confirm against your program’s thesis handbook before submission.
Frequently asked questions
Does Chapter 1 use a different citation style from later chapters?
No. One citation style applies to the entire thesis. Chapter 1 uses the exact same in-text and reference formatting as your literature review, methods, and discussion chapters. Only the content of what you cite differs.
How many citations should Chapter 1 have?
There is no fixed number, but introductions are usually citation-dense because they establish context and justify the study. Cite every borrowed fact, statistic, definition, and theory. Ten to thirty citations is common, depending on discipline and thesis length.
Do I list Chapter 1 references separately?
No. A thesis has one combined reference list or bibliography at the end covering every chapter. You do not create a separate list per chapter. Each in-text citation maps to a single entry in that unified list.
How do I cite a source I only mention in the introduction?
Cite it the same way as anywhere else: an in-text citation at the point of use plus a full entry in the reference list. A source cited once in Chapter 1 still needs a complete reference.
Should I cite the page number in Chapter 1 in-text citations?
Include a page number for direct quotations and specific paraphrased passages. APA and MLA require it for quotes; Chicago notes always give the page. For broad ideas referenced generally, author and year (or author alone in MLA) is enough.
Can I cite another thesis in my Chapter 1?
Yes. Citing prior dissertations is common for demonstrating the research gap. Use the thesis-specific reference format for your style, and note whether it was retrieved from a database or held unpublished at the awarding institution.
