title: [Bibliometric indicators of production and usage of Archivos de Bronchoneumologia].
abstract: We studied the bibliometric indexes referring to production and scientific output published in ARCHIVOS de BRONCONEUMOLOGIA. All issues published between 1993 and 1994 were studied with the exception of monógraphic or supplementary numbers. For each article we recorded article type, number of authors, authors' place of work, specialty, time until acceptance, time until publication, type of references, language of references, journal and year of references. For each year we calculated the productivity index and the cooperation index, or index of signers per work. We also determined the citation period for references, the Price index, and the insularity index. Productivity index was 1.97 in 1993 and 2.05 in 1994. The cooperation index for the two years reached 4.5 +/- 1.9 (1-10). Authors were widely distributed by provinces and by specialties, although "nuclei" of production could be identified. The citation half-life period was 5.67 years for references in 1993 and 5.94 years in 1994, and the Price index surpassed 40%. The insularity index was very low at 7.76%. In conclusion, the bibliometric indicators for production, readership and obsolescence for the two years analyzed indicate that ARCHIVOS de BRONCONEUMOLOGIA occupies an intermediate position in the ranking of Spanish medical journals.
