title: [Analysis of the impact of Archivos de Bronconeumología through the Science Citation Index].
abstract: OBJECTIVE
  To describe the impact factor of Archivos de Bronconeumología from 1997 until 2000 and to identify the patterns of citation of the journal and topics having the greatest impact.
  
  
  METHODS
  SCISEARCH was used to locate citations of articles published by Archivos de Bronconeumología between 1995 and 1999. The following data were collected for each article: year of publication, authors, journal, country of publication, language, specialty or specialties, institution(s), residence of the first author and topic. The impact factor was calculated as the ratio of citations received in one year by articles published in Archivos de Bronconeumología during the two previous years and the total number of articles published by Archivos de Bronconeumología over the two years under study.
  
  
  RESULTS
  The impact factor of Archivos de Bronconeumología was 0.107 in 1997, 0.089 in 1998, 0.105 in 1999 and 0.119 in 2000. Citations were found in a wide range of source journals, with respiratory system publications having little weight. Citations were made mainly by Spanish authors (75%) and self-citation was restrained (21.1%). Topics related to tuberculosis and respiratory infections (23.6% of the citations received) and chronic obstructive pulmonary disease (12.5%) made the greatest impact.
  
  
  CONCLUSIONS
  The impact factor of Archivos de Bronconeumología is modest, although higher than those of some other publications included in Journal Citation Reports.
