"How to publish a scientific article for free?" - is a question that concerns all scientists without exception. Throughout their careers, researchers face high publication fees. Few academics are aware of the opportunity to publish an article at little or no financial cost. In this article, we will look at free publishing options, including open access journals and other resources.

Top 5 ways to publish a research article for free
Publishing a scientific article for free is possible in various ways. Let's consider the main ones:
1. Posting an article in Open Access journals (Open Access)
Open Access (Open Access) journals are scientific publications that provide all readers with free access to published articles. Publication costs are most often borne by the author. But there are a number of publications that provide free publication for the researcher. Most often funding for such journals is provided by universities or covered by government grants.
Examples of journals that provide grants for scientists who cannot pay publication fees: PLOS ONE, BioMed Central, Frontiers.
2. Directory of Open Access Journals (DOAJ)
This directory contains a list of peer-reviewed open access scientific journals, most of which do not require a publication fee. The database includes scientific publications represented by 134 countries, published in 80 languages.
DOAJ indexes:
> 20,000 scientific journals
> 13,000 publications without editorial fees
> 10 million scientific articles.
The DOAJ Scholar Service serves two primary functions: the broad dissemination of scientific knowledge and the ability for researchers to find peer-reviewed journals without publication fees that meet high standards of academic publishing.
Coverage of the online catalog extends across disciplines, including natural sciences, engineering, medicine, social sciences, and humanities. And each journal undergoes a rigorous selection and review process to ensure it meets quality criteria.
3. Institutional repositories
Academic repositories are online databases that store and make available scholarly works. Many universities and scientific organizations have repositories where researchers can publish their articles for free. This increases the visibility and citation of research.
Institutional repositories have two significant advantages:
- Fee-free basis: publishing and placing an article in a repository usually involves no financial outlay
- Accessibility: papers posted in academic repositories are accessible to a wide scientific audience, which also affects the visibility and citability of publications.
4. Participation in academic conferences
Some conferences publish proceedings that can be found in the public domain. Often these publications do not require payment from the authors.
Research available conferences in your field and read their publication requirements carefully. Attending conferences also helps you get feedback from colleagues and make important scientific contacts.
5. Grants and financial support for researchers
Some research grants cover not only the costs of conducting research but also its publication in open access journals. It is possible to find sponsoring organizations and get acquainted with the terms of financial support, research topics sponsored by government and commercial structures on the two main scientific metrics platforms - Scopus (Documents section) and Web of Science (Grants Index section).
Minuses of "free" publication
By choosing one of the above methods, a scholar runs the risk of encountering some of the complexities of free publication. Namely:
- Limited choice of scholarly journals for article submission: open access journals that do not require payment for publication are significantly fewer compared to paid options. This limits the choice of suitable publications, especially for highly specialized research
- Competition for publication slots: popular journals without editorial fees often receive a large number of submissions, which increases competition for publication slots and makes the selection process more rigorous and time-consuming.
- lengthy review process:choosing one of the ways to publish a scientific article for free a scientist may face a long wait for a response from reviewers. Sometimes the feedback has to wait months or even years, which can delay the achievement of scientific goals - defending a dissertation, getting an academic position or funding future research.
It is possible to publish an article for free if you have plenty of time and patience. If you need urgent publication by certain deadlines, you should start the publication process in advance or contact specialists in the field of scientific consulting.
