Academic journals are the lifeblood of academia and research, serving as essential platforms for sharing discoveries and innovations. For science fields like physics, biology, chemistry, engineering, and mathematics, academic journals are central to developing and disseminating knowledge. With so many scientific disciplines and sub-disciplines, it’s no surprise that thousands of journals are dedicated solely to science, technology, engineering, and mathematics (STEM). But how many science journals are there currently publishing?

We have estimated the number of humanities journals before. This write-up dives into the numbers, types, and trends of science-focused academic journals. We’ll explore their evolution, the influence of digital publishing, and the critical role they play in advancing science and technology. If you’re curious about the scale and variety of science journals, this guide will give you a clearer understanding.

A Brief History of Academic Journals

The history of academic journals traces back to the 17th century when journals like Philosophical Transactions of the Royal Society (1665) and the Journal des Sçavans were established. These journals’ primary aim was to share research findings and spark debate among scientists—a goal that remains relevant today. The idea quickly took hold, leading to the establishment of journals across Europe, initially covering general science and later focusing on specialized fields as science became more compartmentalized.

In the 20th century, the scholarly journal landscape expanded significantly as research fields grew in number and specialization. This diversification gave rise to journals that focused solely on specific science fields such as physics, chemistry, medicine, and engineering. Today, these journals are crucial for career advancement, knowledge dissemination, and setting standards in research.

Estimating the Total Number of Science Journals

Determining the exact number of active science journals can be challenging due to the continuous creation of new titles and the closure of less successful ones. However, several key estimates provide a sense of the scale:

  • International estimates suggest over 20,000 active, peer-reviewed science journals worldwide, with the International Association of Scientific, Technical, and Medical Publishers (STM) reporting over 30,000 STEM-focused journals that exist today.
  • Considering other languages, regional publications, and smaller independent journals not counted in English-focused studies, the number of science-only journals could exceed 35,000 worldwide.

This number constantly changes as new journals are launched, particularly online, and as older, less successful ones are phased out. The field continues to grow by about 3-5% annually, especially with the advent of digital publishing, which makes it easier to create and distribute new academic journals.

Types of Scientific Journals: Exploring the Range

To better understand this landscape, it helps to categorize science journals based on their focus, publication model, and accessibility.

1. General Science Journals

These journals cover various scientific disciplines and often publish groundbreaking research relevant to multiple fields. Nature, Science, and Proceedings of the National Academy of Sciences (PNAS) are some of the most recognized general science journals. Articles published in these journals tend to be high-impact and broadly accessible, targeting scientists across diverse fields.

2. Specialized or Field-Specific Journals

As scientific research has grown more specialized, so too have journals. Today, nearly every scientific discipline has journals dedicated to its specific field. Examples include:

  • Physics Review Letters for physics
  • Journal of Chemical Physics for chemistry
  • IEEE Transactions on Neural Networks for computer science and engineering
  • Journal of Biomedical Engineering for medical engineering

These journals allow researchers within a field to stay up-to-date on specialized developments and publish highly technical research that may not appeal to a broader audience.

3. Review Journals

Unlike traditional journals that publish original research, review journals focus on synthesizing and summarizing existing research in specific areas. For example, Annual Review of Biophysics or Trends in Biotechnology provide comprehensive overviews of recent advances, emerging trends, and key debates within their respective fields. These journals are invaluable for researchers seeking a broad understanding of a topic or wanting to catch up on recent developments.

4. Open Access Journals

The open-access movement has significantly changed the science journal landscape by making research available to the public for free. Major open-access journals in the sciences include:

  • PLOS ONE
  • Scientific Reports
  • Nature Communications

These journals are funded through author fees rather than subscriptions, making research available to anyone with internet access. Today, over 12,000 science journals operate as open-access publications, reflecting a growing trend toward greater accessibility and transparency in science.

5. Hybrid Journals

Hybrid journals offer a middle ground between traditional subscription models and open access. Authors can pay for their articles to be available freely (open access) while the rest of the content remains subscription-based. This model is common among large publishers like Elsevier, Springer, and Wiley, allowing researchers to choose how their work is accessed.

The Role of Digital Platforms in Expanding Scientific Journals

The rise of digital publishing has had a profound impact on scientific journals. With online platforms, journals no longer face the same logistical and financial challenges as print publications, allowing for faster and broader dissemination of research findings.

Open Access and Electronic Journals

The open-access model is one of the most influential shifts in digital publishing. It makes research freely available and allows researchers in developing countries and smaller institutions access to the latest findings. Open access has grown dramatically over the past two decades, with more than 20% of new science journals following this model.

Preprint Repositories and Rapid Dissemination

Preprint servers like arXiv (for physics and mathematics) and bioRxiv (for biology) allow researchers to share findings before formal peer review, enabling faster communication of ideas and findings. While preprints don’t replace peer-reviewed journals, they supplement traditional journals by speeding up information sharing, particularly in fields like biomedical science, where timely discoveries can be essential.

Enhanced Access through Digital Archives and Repositories

Universities and research institutions increasingly host digital repositories where research articles, often free to access, are archived. These repositories make storing and distributing their work easier for journals and researchers.

Measuring the Impact of Science Journals

With such a wide range of journals available, assessing their quality and impact is crucial. Various organizations index and rank journals based on metrics that reflect their influence and credibility within the scientific community.

Common journal metrics include the following:

1. Journal Impact Factor

The Journal Impact Factor, often used to measure journal prestige, reflects the average number of citations an article receives. It is particularly useful for identifying high-quality journals, though it tends to favor certain fields and isn’t always the best indicator of research quality.

2. h-index and g-index

h-index and g-index assess a journal’s number of publications and citations, offering a broader measure of influence.

3. Altmetrics

Alternative metrics or “altmetrics” track online mentions, social media interactions, and news coverage, providing a sense of a journal’s engagement beyond the academic sphere.

By relying on these metrics, researchers, funding agencies, and institutions can make more informed decisions about where to publish, what to read, and which research to prioritize.

As technology and publishing models evolve, the world of science journals is likely to undergo further transformation. Here are some trends shaping the future of STEM journals:

1. Transparency in Peer Review

Journals increasingly adopt open peer review models, where reviewer comments are published alongside articles, making the review process more transparent and accountable.

2. Greater Focus on Data Sharing and Reproducibility

Journals require that authors share data, code, and methods to ensure reproducibility. This practice helps validate findings and enhances the credibility of published research.

3. AI and Automated Tools in the Review Process

Artificial intelligence is being integrated into journal and academic publishing, assisting with plagiarism checks, identifying errors, and analyzing statistical accuracy. AI has the potential to streamline the editorial process, making it faster and more reliable.

4. Diversity and Inclusion Initiatives

Many journals are working to increase diversity in authorship, review panels, and editorial boards. This shift toward inclusivity aims to represent a broader spectrum of voices, perspectives, and global research.

Conclusion

The world of science journals is vast, with over 30,000 peer-reviewed publications covering an extensive array of topics within science, engineering, technology, and mathematics. This landscape reflects the diversity and growth of scientific research worldwide, with journals tailored to nearly every conceivable niche in the scientific spectrum.

As digital publishing, open access, and innovative publishing technologies continue to shape the future of scientific publishing, the journal landscape will likely continue expanding, offering new ways to access, publish, and share scientific knowledge. Whether you’re a researcher seeking the right platform for publication or simply a curious reader, the ever-evolving world of academic and science journals ensures that knowledge will continue to be accessible, dynamic, and impactful.
