Referencing ebooks without page numbers

👉 Page numbers can now be provided for in-text citations using the same steps listed in the section above. Go back.

In the rare case that page numbers are still not available for the eBook you’re citing​, most academic referencing styles suggest using the narrowest location reference to cite when page numbers are unavailable, such as the chapter or section.

Examples of how to do so in 6 popular styles

APA 6 & 7

Include either the section title, paragraph number or a combination of the two.

  • Citing a paragraph number:

    • Place the paragraph number – abbreviated to “para.” – after the date of publication

    • Example:

      • (Prothero, 2019, para. 5)

  • Citing a section title:

    • Place the section title – followed by the word “section” – after the publication date

    • Example:

      • (Prothero, 2019, From Dinosaurs to Birds section)

  • Citing texts with long titles:

    • Abbreviate the heading and place it within quotation marks

    • Example:

      • “The Importance of Dinosaurs in Evolutionary Theory” 👉 (Prothero, 2019, “The Importance of Dinosaurs” section, para. 4)

Harvard

Despite being one of the most commonly used referencing styles, there is no single or definitive version of Harvard style, its usage varies from institution to institution. Therefore, it is important to consult your university or academic institution’s Harvard formatting guidelines before starting your project.

  • Citing from a book with no page numbers:

    • Include either the section title, paragraph number, or a combination of the two

    • Example:

      • (Prothero, 2019, para. 5)

      • or (Prothero, 2019, From Dinosaurs to Birds section, para. 4)

  • Citing texts with long titles:

    • Abbreviate the heading and place it within quotation marks

    • Example

      • “The Importance of Dinosaurs in Evolutionary Theory” 👉 (Prothero, 2019, “The Importance of Dinosaurs” section, para. 4)

Chicago

Include the section title, chapter or paragraph number, or a combination of the three.

  • Citing books consulted online:

    • Include a URL at the end of your reference

    • Remember to abbreviate chapter to “chap.” and paragraph to “para.”

    • 1st Footnote Example:

    • Subsequent Footnote Example:

      • (Prothero, Story of the Dinosaurs, chap. 4, para. 2)

Turabian

Include the section title, chapter or paragraph number, or a combination of the three.

  • Citing books consulted online:

    • Remember to abbreviate chapter to “chap.” and paragraph to “para.”

    • Example:

      • (Prothero 2019, para. 5)

      • (Prothero 2019, chap. 4)

OSCOLA

Include the section title, chapter or paragraph number, or a combination of the three.

Unlike most referencing styles, OSCOLA (The Oxford University Standard for Citation of Legal Authorities) does not require you to use any punctuation marks between chapter, paragraph and number.

  • Citing book consulted online:

    • Abbreviate chapter to “ch” and paragraph to “para”, remembering to leave a space before the number

    • Example:

      • Donald R Prothero, The Story of the Dinosaurs in 25 Discoveries: Amazing Fossils and the People Who Found Them (Columbia University Press 2019) ch 1, para 4.
