Bibliometric analysis
Bibliometric analysis is the quantitative evaluation of academic literature, using statistical methods to map citation networks, assess research impact, and track scholarly trends over time.
The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
Core methods and citation metrics
Bibliometric analysis relies on two main approaches: performance analysis and science mapping. Performance analysis evaluates the productivity and impact of research constituents, such as authors, institutions and journals, using indicators like publication counts and citation rates. Science mapping focuses on the relationships between these constituents, examining the structure and dynamics of scientific fields. Together, these methods translate complex arrays of publication data into actionable summaries of scientific progress. Researchers use these quantitative tools to identify major trends, evaluate the impact of scientific discoveries, and assess the return on academic investments, providing a solid foundation for institutional research policies. This analytical approach provides a mathematical framework to evaluate how scientific discoveries spread and influence subsequent scholarly work.
Science mapping and network analysis
Science mapping uses citation networks to visualise how research fields interact. Common techniques include co-citation analysis, which tracks how often two papers are cited together by a third, indicating conceptual links. Bibliographic coupling occurs when two papers reference the same third paper, suggesting shared themes. Co-author analysis maps collaboration patterns, revealing how research clusters form geographically and institutionally across disciplines. These network maps allow scholars to see the structural relationships within a field, highlighting central figures, emerging sub-disciplines, and areas where collaborative networks are expanding, which helps in planning future research activities. This visualization makes it easier to comprehend complex intellectual connections that are often obscured in standard publication lists.
Applications in research and policy
Institutions and funding bodies use bibliometrics to assess academic impact and make strategic decisions. By tracking where research is cited, evaluators identify emerging fields, evaluate the return on research funding, and compare institutional strengths. Publishers also use this data to evaluate journal performance and detect citation manipulation, ensuring the integrity of the scholarly communication network is maintained. Furthermore, bibliometric findings guide national assessment exercises, helping policy makers distribute funding to the most productive and impactful research programmes, ensuring that public resources are utilised effectively to advance scientific knowledge globally. This reliance on objective citation data helps minimise subjective bias during peer-review panels and institutional funding decisions.

Common misconceptions
What people often get wrong
Often heard: Bibliometric analysis is simply counting the number of citations a paper has received.
Actually: It goes beyond simple counting, using network mapping to study relationships, clusters, co-citations, co-authorships, and the conceptual evolution of disciplines.
Often heard: A high citation count always indicates the scientific quality or validity of a study.
Actually: Citations measure academic attention and utility, not necessarily quality. Papers may be cited frequently for controversial claims, flawed methodologies, or historical review purposes.
Common questions
FAQ
What is the difference between co-citation analysis and bibliographic coupling?+
Co-citation analysis occurs when two older papers are cited together in a newer paper, indicating they share a conceptual link. Bibliographic coupling occurs when two newer papers cite the same older paper, indicating they share a thematic foundation.
How do database choices affect bibliometric analysis?+
The scope of your analysis depends heavily on the source database, such as Web of Science, Scopus or Google Scholar. Each database indexes different journals, disciplines and historical periods, which can alter citation counts and network structures.
