Berlin, 4 October 2012 – The idea behind Patron Driven Acquisition (PDA) is simple: to offer users access to all digital content, but only charge for actual use. In partnership with the University of Hagen, Jülich Research Center, and University of Mannheim, De Gruyter recently completed a one-year trial of PDA, an innovative form of distribution that provides users with full content access prior to purchase.
