Currently, most people picture a papery cuboid when they hear \u201cbook.\u201d But the rise of the ebook means this might change before long. Ebooks are popular with students, for instance, as they\u2019re easy to access (and you don\u2019t have to carry them to lectures). And if you want to cite an ebook in a college paper, you may need to know how this works in Harvard referencing.\nIn-Text Citations\nIn-text citations for ebooks require you to give the author\u2019s surname and a year of publication in parentheses:\nExtinction has an important role in evolution (Darwin, 2012).\nRemember to cite the year the ebook version was released, even if an earlier print edition is available (e.g., the Darwin text cited here was originally published in 1860). As with other books, there\u2019s no need to repeat the author\u2019s name in the citation if they\u2019re already named in the text. And if quoting a source, you should still give page numbers:\nAccording to Darwin (2012, p. 146) extinction has played a role in \u201cwidening the intervals between the several groups in each class.\u201d\nIf the ebook uses section titles or paragraph numbers instead of page numbers, you can give these as a pinpoint citation when quoting a source:\nExtinction has played a role in \u201cwidening the intervals between the several groups in each class\u201d (Darwin, 2007, para. 432).\nThe key thing is that your reader can find the quoted text.\nReference List: Online Ebook\nWith Harvard referencing, the exact details to include in the reference list for an ebook may depend on where you found it. Generally, though, the format is:\nAuthor, Initial(s). (Year) Title of Book [Format], Place of publication: Publisher. Available at ebook source and\/or URL [Accessed date].\nIf you access an ebook online, then, your reference would look like this:\nDarwin, C. (2007) The Origin of Species [online], Salt Lake City: Project Gutenberg. Available at https:\/\/www.gutenberg.org\/files\/22764\/22764-h\/22764-h.htm [Accessed 23 November 2016].\n\nReference List: Ebooks on Readers\nThe format differs for an ebook accessed through an e-reader. In particular, you do not need to give access information such as a URL or database:\nAuthor, Initial(s). (Year) Title of Book [Format], Place of publication: Publisher.\nIn practice, then, your reference would look like this:\nDarwin, C. (2012) The Origin of Species [Kindle], New York: Collins Classics.\nNote that we include the format still, but we don\u2019t provide a URL.\nA Final Note\n\u201cHarvard referencing\u201d is actually just another term for \u201cauthor-date\u201d citations. The exact format to use may thus depend on your school. This makes it vital to check your institution\u2019s style guide, as they may use a version of Harvard referencing that differs slightly from this one.
