Referencing is one such aspect of academic writing which not only allows one to escape plagiarism but also helps in demonstrating the extent of research conducted on the chosen topic. While both APA 7th edition and Harvard styles allow you to structure your reference list appropriately, there are a number of differences you should be mindful of before submitting a manuscript. Referencing is a mechanical exercise that shows your commitment to scholarly writing, and it should be given due attention even before addressing the actual content of your manuscript.
1. Mixing Harvard and APA style
The most common mistake students make while using both citation styles is mixing them with each other, either in the reference list or within the main text. This can happen when you write using notes or sources that were formatted using a different style and subsequently use them without changing the formatting. To avoid this, pick one system and follow it throughout the paper, and confirm that the selected style is what your target publication or university actually requires. For instance, while APA 7th edition uses hanging indents for all entries, sentence-case for journal article titles, and italicization for journal titles and volume numbers, each Harvard-following university can take a slightly different approach to formatting its reference list.
2. Inconsistent use of "and" vs "&" and "et al."
When it comes to the main text, there are several common inconsistencies worth avoiding. APA 7th edition uses "and" within parentheses for two authors, while Harvard typically retains "&" for reference list entries. Both citation styles require "et al." starting from three authors for parenthetical references, which is especially confusing for those who completed their degrees before the latest APA edition. It's important to note that "et al." is used in parenthetical references; when citing three or more authors in the main text itself, you use the abbreviation only within the parenthesis, expanding it to the lead author's name followed by "et al." otherwise.
3. Omitting DOI and retrieval information
Both citation styles require you to include the DOI (digital object identifier) for cited work. Pay special attention here, since the latest APA edition made significant changes: it now recommends providing the DOI as a URL, meaning "doi:" is no longer used before the identifier. Retrieval information is only needed for online resources. For Harvard, each university following the style may have specific requirements around including retrieval information, including the date of access for online resources.
4. Mishandling secondary sources
Both citation styles take slightly different approaches to secondary sources, works you didn't directly access but that were cited by someone else in their paper. APA 7th edition handles this by indicating "as cited in," while other styles, including Harvard, may have different conventions worth learning before submission.
5. Missing page numbers on quotes and paraphrases
Both styles require page numbers for direct quotations, but they're often neglected when paraphrasing information from a specific page. Many institutions also require page or paragraph numbers for paraphrased content, so it's worth becoming familiar with your target publication's requirements. When in doubt, it's always advisable to include the page number where a piece of information was located in the source.
6. Leaving referencing until the end of the writing process
Avoiding common citation mistakes isn't a task that requires substantial time just before submission. Instead, build a sustainable habit of proper referencing from the very start, using reference management software such as Zotero, Mendeley, or EndNote. Select your target style, APA 7th edition or the specific Harvard variant required by your journal or university, as early as possible, and use it consistently throughout the writing process. This saves you from spending hours formatting a reference list at the very end.
7. Not paying attention to formatting in the papers you read
Beyond consistency in your own writing, it helps to build a habit of noticing proper formatting when reading journal articles in your field. Learning how different source types, journal articles with three authors, books with no dates, and so on, are formatted under your chosen style makes you more familiar with what a properly formatted reference list actually looks like.
8. Skipping a dedicated proofreading pass for citations
Citation consistency is an integral part of academic writing, and it rarely requires extra time beyond your regularly scheduled proofreading. It's much easier to prevent an issue than to solve it, so a brief, focused proofread of your reference list before submission can help you avoid problems that would be much harder to fix later. Minor inconsistencies rarely pose a serious problem on their own, but their cumulative impact on the overall impression of the work shouldn't be ignored. A reference list with a number of issues won't read as polished as a well-formatted one, and that changes how the manuscript is perceived as a whole.
For anyone looking to publish in their field or further their scholarly career, proper referencing leaves a lasting impression on readers. It's a skill that, once built, pays off across every research paper you go on to write. Avoiding these common citation mistakes is often easier than it first appears, especially with the support of language editing services that can catch inconsistencies with ease.
