[Half a century of ANALES DE PEDIATRÍA. Evolution of its main bibliometric indicators in the Web of Science and Scopus international databases].

PURPOSE: To analyse the coverage and main bibliometric indicators of ANALES DE PEDIATRÍA in Scopus and Science Citation Index Expanded of the Web of Science (SCIE) databases.

MATERIAL AND METHOD: The evolution of the journal production was identified according to the document types, collaboration indexes between authors and institutions, and citations, and impact indicators (number of citations, impact factor, 5-years impact factor and without self-citations, Scimago Journal Rank, quartile, h index and most cited works).

RESULTS: A total of 10,128 papers were included in Scopus (a mean of around 225 per year) and 1,861 in SCIE (a mean of around 207 per year). The index of collaboration was 4.4 for authors and 2 for institutions. There was international collaboration in 4.2% of the papers. The number of citations received in Scopus (619) exceeded the number of citations received in SCIE (385) by 234. The mean number of citations per paper was lower in SCIE (2.27 in Scopus compared to 1.5 in SCIE). The h index was 18 in Scopus and 14 in SCIE.

CONCLUSIONS: Discrepancies were observed in the indicators obtained in both databases due to the different indexation policies, coverage, and classification methods of the papers. The number of citations, the mean number of citations per work, and the h index were higher in Scopus due to the longer life of the journal in that database. There is a positive evolution of the impact factor in SCIE, of the impact factor excluding self-citations, and of the 5-year impact factor.
