We present a bibliometric study of a corpus of 839 bibliographic references about automatic
indexing, covering the period 1956-2000. We analyse the distribution of authors and works, the
obsolescence and its dispersion, and the distribution of the literature by topic, year, and source
type. We conclude that: (i) there has been a constant interest on the part of researchers; (ii) the
most studied topics were the techniques and methods employed and the general aspects of
automatic indexing; (iii) the productivity of the authors does fit a Lotka distribution (Dmax =
0.02 and critical value = 0.054); (iv) the annual aging factor is 95%; and (v) the dispersion of
the literature is low.

Keywords: Automatic indexing; Scientific output; Bibliometric analysis
