[Bibliometry of biomedical periodicals]

Area of Science:

• Bibliometrics
• Scientometrics
• Information Science

Background:

• Bibliometrics, also known as the Science Citation Index, provides quantitative evaluation of scientific literature.
• It relies on citation analysis to derive indices for journal classification and impact assessment.

Purpose of the Study:

• To define bibliometrics and its applications in evaluating literature and research.
• To highlight the intrinsic limitations and potential biases of bibliometric indices.
• To emphasize the necessity of qualitative criteria alongside citation analysis for accurate research appraisal.

Main Methods:

• Quantitative analysis of citations to characterize and classify journals.
• Calculation of various bibliometric indices (e.g., impact factor, topicality).
• Discussion of qualitative and semi-quantitative methods for content analysis (e.g., critical reading).

Main Results:

• Bibliometric indices can be used to assess journal significance, national contributions, and research impact.
• Citation analysis alone is insufficient for evaluating research quality due to inherent biases.
• Prestigious journal publication does not guarantee article quality (relevance, methodology, accuracy).

Conclusions:

• Bibliometrics is a valuable tool for quantitative literature evaluation but has inherent limitations.
• Over-reliance on bibliometric indices for research quality assessment can be misleading.
• A balanced approach combining quantitative bibliometrics with qualitative content analysis is recommended for comprehensive research evaluation.
