摘要：This paper analyses the development of Spanish research literature in the field of citation analysis and impact factor (IF) in biomedicine over the period 1981-2005. Bibliometric methods and social network analysis were used to examine papers indexed in the Science Citation Index-Expanded (SCI-Expanded), Social Sciences Citation Index (SSCI), MEDLINE, Índice Médico Español (IME) and Índice de Ciencias Sociales y Humanidades (ISOC) databases. 184 papers were identified, 79.89% of which were original research articles. Only four of these papers had been published before the 1990s. The mid 1990s saw a remarkable increase in the number of papers published (8-14 papers/year) with the highest productivity being reached from 2002 onwards (14-25 papers/year). The IME and SCI-Expanded/SSCI databases were those recording the largest numbers of papers, both in absolute (67.93% and 40.76 respectively) and singularity terms (42.39% and 21.74% respectively). The detected papers were published in 76 Biomedical and Documentation journals (82.06% and 15.22% respectively). The most productive authors were identified along with the main co-authorships and institutional collaboration networks operating in the field. These results are related to the importance of impact factor at both national and international level.
