The Power Behind the Word “Indexed”
In the world of scholarly publishing, few words carry as much weight as “indexed.” For many researchers, the first question they ask when choosing a journal is simple: Is the journal indexed? The answer to this question can influence not only where authors submit their work, but also how their research is perceived by institutions, funding agencies, and promotion committees.
Yet the systems that determine what counts as “indexed” are rarely examined closely. Behind the scenes lies a complex infrastructure of citation databases and indexing services that shape the visibility of scholarly work across the world. Major discovery platforms such as Scopus, Web of Science, and OpenAlex have become central tools for navigating the global research literature.
As global research output expands rapidly, particularly in regions such as Asia, Africa, and Latin America, an important question emerges: should global scholarly visibility depend on only a small number of centralized indexing systems, or is there room for a more diverse and inclusive indexing ecosystem?
The Invisible Infrastructure of Scholarly Visibility
Indexing databases are among the most influential yet least visible components of the scholarly communication system. They function as the navigation infrastructure of research, helping scholars discover literature, enabling libraries to organize collections, and allowing institutions to track research impact.
Over time, indexing status has become deeply embedded in academic culture. Journals often seek inclusion in well-known indexing systems as a marker of credibility, while researchers rely on indexed journals to ensure that their work reaches the widest possible audience. Universities and funding bodies frequently incorporate indexing status into research evaluation systems, reinforcing the importance of these databases.
As a result, indexing databases serve not only as discovery tools but also as gatekeepers of scholarly legitimacy.
The Dominance of Global Citation Indexes
For decades, a relatively small number of global citation databases have dominated the indexing landscape. Platforms such as Scopus and Web of Science have played a crucial role in organizing the rapidly growing body of scientific literature and have contributed significantly to the development of modern research evaluation frameworks.
However, the concentration of influence within a limited number of indexing platforms has also created challenges. As the volume of scholarly publishing continues to expand, it becomes increasingly difficult for centralized systems to capture the full diversity of global research output.
The rapid growth of research production in Asia provides a clear example. Universities and research institutes across the region are producing an unprecedented volume of scientific publications. Yet many journals representing regional research communities remain underrepresented in global indexing systems.
This situation raises an important question: can a small number of global indexing databases adequately represent the expanding geography of scientific research?
The Emergence of Regional Citation Databases
In response to these challenges, several regional indexing initiatives have emerged in recent years. These databases aim to improve the discoverability of research produced within specific geographic or disciplinary contexts.
Regional citation databases often serve multiple purposes. They highlight research relevant to regional challenges, support journals that serve local scientific communities, and provide additional visibility for emerging publications that may not yet be indexed in larger global systems.
Rather than replacing global indexing databases, regional initiatives can complement them by addressing gaps in coverage and improving access to regionally relevant scholarship. They also help strengthen local scholarly infrastructures by encouraging higher editorial standards and promoting responsible publishing practices.
The Role of the Asian Science Citation Index (ASCI)
One example of such an initiative is the Asian Science Citation Index (ASCI). Developed to improve the visibility of scholarly journals from Asia, ASCI aims to support the rapidly expanding research landscape of the region.
Asia has become one of the most dynamic contributors to global science, with universities and research institutes producing an increasing share of the world’s scientific output. However, many regional journals continue to face challenges in achieving international visibility.
Regional indexing initiatives such as ASCI seek to address this imbalance by providing a structured platform for the discovery of scholarly journals and articles produced within the region. By improving the accessibility of these publications, such systems contribute to a more balanced representation of global research.
Importantly, the objective of these initiatives is not necessarily to compete with existing global databases but to complement the broader scholarly ecosystem.
Regional Citation Databases as Development Ecosystems for Journals
Beyond improving visibility for regional research, regional citation databases may also serve another important function within the scholarly publishing ecosystem. They can operate as development environments for emerging journals, allowing editorial teams to strengthen publishing practices, improve peer review systems, and build citation networks before seeking inclusion in larger global databases.
In this sense, regional indexing systems can act as early-stage ecosystems for journal development. By indexing journals that demonstrate sound editorial policies but are still developing their international presence, regional databases provide an opportunity for these publications to mature and improve over time.
For global citation databases, this process can also be advantageous. Instead of identifying promising journals from an extremely large and heterogeneous global pool, they may increasingly encounter journals that have already undergone an initial phase of editorial development and visibility through regional indexing initiatives.
Journals that progress through such ecosystems may reach global databases with stronger peer review practices, improved publication consistency, and clearer editorial governance.
From this perspective, regional citation databases should not necessarily be viewed as competitors to global indexing systems. Rather, they can function as complementary layers within the scholarly infrastructure, helping to cultivate high-quality journals from diverse regions while making it easier for global databases to identify mature and well-managed publications.
In a rapidly expanding research environment, such layered indexing ecosystems may ultimately reduce the burden on centralized databases while simultaneously improving the overall quality and diversity of journals entering the global scholarly record.
The Debate Around “Recognized” Indexing Databases
The growth of regional citation databases inevitably raises an important policy question: who determines which indexing systems are recognized or legitimate?
Historically, many of the most influential indexing systems were developed within specific academic and geographic contexts. As these systems gained widespread adoption, they naturally acquired authority in defining indexing standards.
However, the global research landscape has evolved dramatically. Today’s scholarly ecosystem is far more geographically diverse than it was several decades ago. Researchers in many regions are increasingly questioning whether a small number of centralized indexing systems should continue to dominate the global visibility of research.
These discussions form part of a broader debate about governance within scholarly publishing. As research communities expand worldwide, the infrastructure that supports them may also need to become more inclusive and representative.
Responsibilities of Emerging Citation Indexes
While regional indexing initiatives offer important opportunities, they also carry significant responsibilities. Any indexing database, whether global or regional, must operate with transparency and clear governance.
Researchers and publishers must be able to understand how journals are selected, what criteria are applied, and how indexing claims are communicated. Without clear standards, confusion may arise between indexing services and journal metrics, potentially undermining trust in the scholarly system.
For emerging citation databases to gain credibility, they must prioritize transparency, maintain rigorous inclusion criteria, and clearly distinguish indexing functions from impact metrics.
Toward a More Plural Scholarly Infrastructure
The expansion of regional citation databases may signal a broader transformation in the architecture of scholarly communication. Rather than relying exclusively on a small number of centralized platforms, the future indexing ecosystem may involve multiple interconnected systems working together to improve research visibility.
Such a pluralistic model could offer several advantages. It would allow regional research communities to develop infrastructure tailored to their needs while still connecting with global discovery systems. It could also reduce the bottleneck effect created when thousands of journals compete for inclusion in a limited number of centralized databases.
Most importantly, a more diverse indexing landscape could help ensure that scholarly visibility reflects the full diversity of global research.
Rethinking the Global Indexing Landscape
Indexing systems play a crucial role in shaping how scientific knowledge is discovered, evaluated, and disseminated. Yet as the geography of research continues to expand, the infrastructure that supports scholarly visibility must also evolve.
Regional citation databases such as the Asian Science Citation Index (ASCI) represent one response to this challenge. By improving the discoverability of regional scholarship and supporting the development of emerging journals, these initiatives contribute to a more inclusive and resilient scholarly ecosystem.
Rather than viewing regional indexing initiatives as competitors to established systems, it may be more productive to see them as complementary components of a layered global infrastructure, one that allows journals to grow, mature, and eventually participate more fully in the international research conversation.
In an era of rapidly expanding scientific production, the future of scholarly visibility may depend not on a single dominant indexing authority but on a diverse and interconnected network of indexing systems that collectively reflect the evolving landscape of global research.
