Friesike and Schildhauer
(2015) suggest that wider
range of quantitative
indicators of a wider range of
impact can be incentivizing for
researchers to make their
research more accessible,
adopting the open science

Our preliminary results are
based on an analysis of how
almost 4 million altmetric events
are spread between articles in
open access journals (as listed by
DOAJ) and other journals.

• A great deal of Wikipedia articles are
written by researchers with paid access to
research articles (additional evidence of
the high quality of Wikipedia articles?).
