How to Cite a Map in APA: A Step-by-Step Guide
Introduction
Maps are essential tools for conveying spatial information, whether for academic research, professional projects, or personal use. Properly citing maps in APA (American Psychological Association) style ensures credibility, allows others to locate the source, and upholds ethical standards in scholarship. This guide provides a comprehensive overview of how to cite maps in APA format, including both print and digital sources.
Understanding APA Style
APA style is widely used in the social sciences, education, and other disciplines. It emphasizes clarity, consistency, and precision. While APA primarily focuses on citing books, journal articles, and online sources, it also provides guidelines for non-textual materials like maps. The key is to include enough information for readers to identify the map’s origin, creator, and publication details Surprisingly effective..
Types of Maps and Their Citation Requirements
Maps can vary in format, and the citation method depends on the type of map and its source. Common categories include:
- Print maps (e.g., physical or topographic maps from books, atlases, or standalone publications).
- Digital maps (e.g., online maps from websites, GIS platforms, or interactive tools).
- Historical maps (e.g., archival or vintage maps from collections or libraries).
- Maps from government or institutional sources (e.g., U.S. Census Bureau or National Geographic).
Each type requires specific elements in the citation, such as the map’s title, author, publisher, and access information.
Citing a Print Map in APA
For a print map, the citation follows the standard APA format for a book or article. Here’s how to structure it:
Format:
Author(s). (Year). Title of the map (Map). Publisher.
Example:
Smith, J. (2020). Topographic map of the Rocky Mountains (Map). National Geographic Maps.
Key Elements:
- Author(s): The creator of the map. If the author is an organization (e.g., a government agency), list the organization as the author.
- Year: The publication or creation year of the map.
- Title: The map’s title, italicized. If the map is part of a larger work (e.g., a textbook), include the title of the larger work in italics as well.
- Publisher: The entity that produced or distributed the map.
Example with a Book Containing a Map:
If the map is included in a book, cite the book and note the map’s title in the text. For example:
"According to Johnson (2018), the map of the Amazon River (p. 45) illustrates the region’s waterways."
Citing a Digital Map in APA
For digital maps, include the URL and the date of access. The format is similar to citing a website but with additional details about the map’s source Worth keeping that in mind..
Format:
Author. (Year). Title of the map [Map]. Website Name. URL
Example:
U.S. Census Bureau. (2023). Population distribution map of the United States [Map]. U.S. Census Bureau. https://www.census.gov/data/maps.php
Key Elements:
- Author: The creator or organization responsible for the map.
- Year: The publication or last update year.
- Title: The map’s title, italicized.
- Website Name: The name of the website hosting the map.
- URL: The direct link to the map.
- Access Date: If the map is likely to change over time, include the date you accessed it.
Example with a Historical Map:
For historical maps, include the repository or archive where the map is stored. For example:
"Library of Congress. (1890). Map of the United States during the Civil War [Map]. Library of Congress. https://www.loc.gov/maps/1890/us-civil-war"
Citing a Map from a Government or Institutional Source
Government or institutional maps often have clear authorship and publication details. Follow the same structure as above but ensure the publisher is accurately identified.
Example:
National Geographic Maps. (2021). World population density map (Map). National Geographic Maps. https://www.nationalgeographic.com/maps/
Citing a Map from a Website or Online Platform
If the map is accessed through a website, include the website’s name and the URL. If the map is part of a larger collection, mention the collection’s title Nothing fancy..
Format:
Author. (Year). Title of the map [Map]. Website Name. URL
Example:
Google Maps. (2023). Interactive map of Paris [Map]. Google Maps. https://www.google.com/maps
Citing a Map with No Author
If the map has no identifiable author, start the citation with the title of the map Small thing, real impact. But it adds up..
Format:
Title of the map. (Year). Title of the map (Map). Publisher.
Example:
"Map of the European Union." (2022). Map of the European Union (Map). European Union. https://ec.europa.eu/map
Citing a Map with Multiple Authors
If the map has multiple authors, list all names separated by commas, with an ampersand before the last author Easy to understand, harder to ignore. Simple as that..
Format:
Author1, A., & Author2, B. (Year). Title of the map (Map). Publisher.
Example:
Brown, T., & Lee, R. (2019). Urban development map of New York City (Map). City Planning Press.
Citing a Map with a DOI
If the map is available through a digital object identifier (DOI), include it in the citation.
Format:
Author. (Year). Title of the map (Map). Publisher. DOI: [DOI number]
Example:
Smith, J. (2020). Topographic map of the Rocky Mountains (Map). National Geographic Maps. https://doi.org/10.1234/56789
Citing a Map from a Library or Archive
For maps stored in libraries or archives, include the institution’s name and the location Worth knowing..
Format:
Author. (Year). Title of the map (Map). Publisher. Library/Archive Name.
Example:
"Map of the Silk Road." (1300). Map of the Silk Road (Map). British Library. British Library, London.
Common Mistakes to Avoid
- Omitting the map’s title: Always include the map’s title in italics.
- Forgetting the access date: For digital maps, include the date you accessed the source if it is likely to change.
- Misidentifying the publisher: Ensure the publisher is correctly named, especially for government or institutional maps.

FAQs
Q1: How do I cite a map from a website in APA?
A: Include the author, year, title of the map, website name, URL, and access date if necessary. Example: U.S
Geological Survey. (2021). Practically speaking, Topographic map of Yellowstone National Park (Map). USGS. https://www.Now, usgs. Now, gov/maps/yellowstone. Accessed October 15, 2023.
Q2: Do I need to include a scale in the citation? A: No, APA style does not require the map scale (e.g., 1:24,000) in the reference list entry. On the flip side, if the scale is crucial for your reader to understand the context of your research, you may mention it in the text of your paper (e.g., "The 1:50,000 scale map shows...").

Title of map (Map) [Description of material if needed]. Repository Name, City, State/Country. Example: Mitchell, S. A. (1846). A new map of Texas, Oregon, and California (Map). David Rumsey Map Collection, Stanford University Libraries, Stanford, CA.
Q4: What if the map is part of a larger work, like an atlas or a journal article? A: Cite the specific map as a chapter or part of a larger work. Use "In" before the editor/author of the larger work. Format: Author. (Year). Title of map (Map). In Editor, E. (Ed.), Title of atlas/book (pp. xx–xx). Publisher. Example: National Geographic Society. (2018). Political map of Africa (Map). In J. Smith (Ed.), National Geographic Atlas of the World (11th ed., pp. 78–79). National Geographic Partners.
Q5: How do I handle a map with no date? A: Use "(n.d.)" in place of the year. Example: Cartography Associates. (n.d.). Historical map of London (Map). David Rumsey Map Collection. https://www.davidrumsey.com
Final Thoughts
Mastering the art of citing cartographic materials is an essential skill for researchers, students, and professionals across disciplines ranging from geography and urban planning to history and environmental science. Maps are unique sources—they are simultaneously visual artifacts, data representations, and historical documents—and APA’s structured format ensures that their distinct attributes (scale, projection, series number, sheet name) are not lost in translation Small thing, real impact..
As digital mapping platforms evolve and historical collections continue to digitize, the line between a "map," a "dataset," and an "interactive tool" will continue to blur. The principles outlined in this guide—identifying the creator, dating the work, describing the format, and providing a reliable retrieval path—will remain the bedrock of credible attribution regardless of the medium. By applying these standards consistently, you not only uphold academic integrity but also honor the cartographers, surveyors, and institutions that make spatial knowledge accessible.
