OA Advantage

Posted in Publicaciones |

Uno de los muchos textos en los que se demuestra que los artículos OA reciben un mayor número de citas. En este caso se argumenta que la razón no es simplemente la mayor accesibilidad, sino la mayor calidad.

ABSTRACT: Articles whose authors make them Open Access (OA) by self-archiving them
online are cited significantly more than articles accessible only to
subscribers. Some have suggested that this "OA Advantage" may not be causal but
just a self-selection bias, because authors preferentially make higher-quality
articles OA. To test this we compared self-selective self-archiving with
mandatory self-archiving for a sample of 27,197 articles published 2002-2006 in
1,984 journals. The OA Advantage proved just as high for both. Logistic
regression showed that the advantage is independent of other correlates of
citations (article age; journal impact factor; number of co-authors, references
or pages; field; article type; or country) and greatest for the most highly
cited articles. The OA Advantage is real, independent and causal, but skewed.
Its size is indeed correlated with quality, just as citations themselves are
(the top 20% of articles receive about 80% of all citations). The advantage is
greater for the more citeable articles, not because of a quality bias from
authors self-selecting what to make OA, but because of a quality advantage,
from users self-selecting what to use and cite, freed by OA from the
constraints of selective accessibility to subscribers only.
