How to use Scopus to view the number of papers in a certain academic field?

Scopus enables researchers to quantify scholarly output within specific academic fields through its comprehensive database and filtering capabilities. Its indexed content and disciplinary classification system support this objective directly. Achieving an accurate count requires correctly identifying the target field using Scopus' predefined subject categories or custom search strategies. Key principles include combining relevant keywords with Scopus All Science Journal Classification (ASJC) codes and document type filters. Essential conditions are choosing precise terminology representing the field and applying appropriate publication date ranges. This method applies to established disciplines with consistent nomenclature, but cross-disciplinary topics may require iterative query refinement. Researchers must verify that Scopus adequately covers their specific field's publication venues. To obtain the count, first access Scopus' Advanced Search. Construct a query incorporating field-specific keywords or exact phrases combined with relevant ASJC codes using the `SUBJAREA()` operator if needed. Then, apply filters like publication years, document type (e.g., article, review), and potentially language. Execute the search; the total number of matching documents displayed above the results list represents the paper count for the defined field and timeframe. This quantification aids bibliometric analysis, trend identification, and research gap discovery.
