Abstract:
Objective: The authors characterized the output of MEDLINE papers by
language and country of publication during a thirty-four-year time period.
Methods: We classified MEDLINE's journal articles by country of publication
(Anglos/Non-Anglos) and language (English/Non-English) for the years 1966
and from 1970 to 2000 at five-year intervals. Eight English-speaking
countries were considered Anglos. Linear regression analysis of number of
papers versus time was performed.

Results: The global number of papers increased linearly at a rate of 8, 142
papers per year. Anglo and English papers also increased linearly (6,740
and 9,199, respectively). journals of Non-Anglo countries accounted for 25%
of the English language increase (2,438 per year). Only Non-English papers
decreased at a rate of 1,056 fewer papers per year. These trends have led
to overwhelming shares of English and Anglo papers in MEDLINE. In 2000, 68%
of all papers were published in the 8 Anglo countries and 90% were written
in English.

Conclusions: The Anglo and English preponderances appear to be a
consequence of at least two phenomena: (1) editorial policy changes in
MEDLINE and in some journals from Non-Anglo countries and (2) factors
affecting Non-Anglo researchers in the third world (publication
constraints, migration, and undersupport). These are tentative conclusions
that need confirmation.
