Wiley has moved further into Open Access (OA) with the $298m (£219m) acquisition of scientific research publisher Hindawi. This deal “significantly increases Wiley’s position as a global leader in research by adding quality, scale, and growth to the company’s open access publishing program.” Hindawi has a portfolio of more than 200 peer-reviewed scientific, technical, and medical journals, plus a “highly efficient” publishing platform. The deal will also double Wiley’s gold OA journal portfolio. In this model, validated articles are made immediately available for reading and re-use following the payment of a publication fee.
