It is quite difficult to assess the scientific productivity of a researcher, as there is always an element of subjectivity in this process. To minimise its influence, a special metric – the Hirsch index (h-index) is widely used in the academic community. Almost every scientist strives to increase this index, as it reflects the level of influence and importance of his/her scientific activity. There are many strategies to increase the h-index, one of which is co-authored publication. Next, we will look at how collaborating with other researchers helps to increase this index.

Is it possible to increase the Hirsch index with co-authored publications?
Many scientists ask whether it is possible to increase the Hirsch index through co-authored publications with other scientists. The answer is unequivocally yes. Co-authorship is one of the most effective strategies to improve this index. It affects a number of factors, which we will discuss below.
We also advise you to read our article in which we detailed the role of the Hirsch Index in a scientist's career.
1. Increasing the number of publications
It is worth starting with the fact that one of the key conditions for increasing the h-index is to increase the number of scientific publications. Without this, it is extremely difficult to improve this indicator, because as the number of articles increases, the probability of their citation also increases. At the same time, writing scientific papers is a labour-intensive and time-consuming process. However, it can be optimised with the help of co-authorship.
Working together with other researchers allows you to participate in more projects, which directly contributes to the growth of the total number of publications. Combining the efforts of scientists with different expertise makes it possible to realise larger and more complex studies.
As a rule, such works are of high quality, receive a greater response in the scientific community and, consequently, have a positive impact on the Hirsch index.
2. Expanding the audience
Another of the advantages of co-authorship is the expansion of the audience of potential readers. It often transcends the boundaries of one discipline or country, forming interdisciplinary and international projects.
- interdisciplinary co-authorship: brings together researchers from different fields, such as biology and computer science. Such projects attract the attention of specialists from related fields, which increases the number of citations.
- international co-authorship: brings research to a global level. Publications co-authored with scientists from other countries gain access to the international scientific community, which contributes to their citation and Hirsch index.
3. Publication in reputable journals
Collaboration with scientists of high scientific standing or from renowned institutions significantly increases the chances of publication in journals with a high impact factor.
Such journals have strict requirements for the quality of articles, but their high reputation ensures greater attention to the published work. Publications in reputable journals are more likely to be cited, which has a positive effect on the h-index.
4. Improving the quality of research
Co-authorship of articles creates an environment for sharing experiences, ideas and research methodologies, which contributes to a deeper elaboration of the scientific problem and increases the scientific value of the publication.
Advantages of co-authorship:
- bringing together different scientific approaches and knowledge;
- more careful checking and editing of the text due to the contribution of several authors;
- the possibility of identifying and correcting errors before publication.
Co-authored publications are often of a higher quality due to collaborative work. This increases their scientific value and makes such articles more attractive to other researchers, which in turn increases citations.
Co-authorship is an effective tool for increasing the Hirsch index, as it increases the number of publications, their quality and citations. Collaborating with other scholars enhances academic opportunities and helps in gaining professional recognition.
