Query: Adoption of the open access business model in scientific journal
  publishing: A cross-disciplinary study   Scientific journal publishers have over the past twenty-five years rapidly
converted to predominantly electronic dissemination, but the reader-pays
business model continues to dominate the market. Open Access (OA) publishing,
where the articles are freely readable on the net, has slowly increased its
market share to near 20%, but has failed to fulfill the visions of rapid
proliferation predicted by many early proponents. The growth of OA has also
been very uneven across fields of science. We report market shares of open
access in eighteen Scopus-indexed disciplines ranging from 27% (agriculture) to
7% (business). The differences become far more pronounced for journals
published in the four countries, which dominate commercial scholarly publishing
(US, UK, Germany and the Netherlands). We present contrasting developments
within six academic disciplines. Availability of funding to pay publication
charges, pressure from research funding agencies, and the diversity of
discipline-specific research communication cultures arise as potential
explanations for the observed differences.
