If you have already published a paper, chances are that you will want to cite it even in the next paper you write. This article discusses the practice of self-citation, i.e., the reference to a previously published article by the same author.
Self-citation might be awkward, especially if you have been brought up in a culture that encourages modestly. There is also evidence to suggest that female academics in particular are relatively reluctant to cite their own work (e.g., a study conducted in 2017 found that men are 70% likelier to self-cite than women). In fact, what prompted this post was a discussion with a junior colleague, who was wondering if citing her own work in an upcoming presentation would be “obscene”.
Would it be too obscene if I cited my paper in my upcoming presentation?
The TL:DR is that, in principle, an author’s responsibility is to direct the readers’ attention to all the relevant research. This is sometimes work in which the author has been involved. So, yes, it is OK to cite your own work.
In the paragraphs that follow, I give a more extended answer, which examines:
- when self-citation may be appropriate, and
- some common abuses of self-citation.
Legitimate self-citation
There are three main reasons why it might be appropriate to cite your own work. These are:
- showing how your new work connects to your research agenda
- alerting readers to how your thinking is evolving
- avoiding textual overlap.
Demonstrating research coherence
One reason why self-citation may be justified is because of the cumulative nature of scientific work. This means that, as long as your research agenda is coherent, your new research will build on what you have learnt (and published) previously. In such cases, citing your older publications is a helpful way of contextualising the new research.
Discussing your previous publications is also be a useful opportunity to point out how the new publication adds to the academic record. Establishing what is new, compared to previous work helps to avoid the impression that you are salami-slicing your research, or publishing lots of essentially similar publications.
Demonstrating conceptual progress
The second reason why you might want to refer to a previous publication is in order to demonstrate how your thinking has evolved. When working on a research topic over a long period of time, you are likely to develop new, more refined understandings. When this happens, you may need to critically re-evaluate your previous publications. If you don’t, that will likely confuse readers, who might not notice subtle conceptual shifts between older and newer publications.
Avoiding overlap
You might sometimes find yourself in a situation where you are describing something very similar to what you have already written in the past. For example, you may need to define a key term, or might have to describe a research procedure that you have used in multiple projects. In such situations, it is better to refer readers to your previous work, rather than repeat things all over. This is especially important in view of the increased sensitivity to self-plagiarism.
How to cite yourself appropriately
All that said, there are a couple of things you need to be cautious about when citing your own work. Firstly, self-citations should add value for the readers. This means that you should not cite your own papers just for the sake of boosting your ego. You should also aboid self-citation for the more insidious purpose of increasing your bibliometric rankings. Some people do this, because the number of times an academic has been cited is sometimes used as an indirect measure of research quality. Excessive self-citation risks annoying reviewers, who may justifiably ask for revisions.
The second thing to remember is that self-citations, when used, should sensibly contextualise your new publication. A common mistake is when a person discusses a well-researched phenomenon, but they only refer to their own work. In some rare cases, the author happens to be the only person who has published about this phenomenon. In most other cases, readers may assume that the author is either unfamiliar with the broader literature, or just trying to self-advertise. Either way, this creates a very negative impression — that of “soliloquising on the scholarly stage“.
The last thing you might want to keep in mind is that your self-citation should not give away your identity, if you’re writing for a journal that practices anonymous (‘blind’) peer-review. Journals will often have specific instructions on how to deal with self-citation. For example, you may be asked to replace your name with “Author”, or to remove first-person pronouns. Some journals, by the way, have policies limiting the use of self-citation, so make sure you read the instructions to the authors very carefully.
The verdict
Provided you do not indulge in gratuitous self-citation, references to your previous publications are perfectly legitimate, and may in some cases be necessary.
