The idea behind Patron Driven Acquisition (PDA) is simple: to offer users access to all digital content, but only charge for actual use. Beginning in 2013, two of De Gruyter's publishing partners - Harvard University Press, and Böhlau Publishers - will offer their content globally through De Gruyter Online as part of the PDA distribution model. By participating in PDA distribution, these publishing houses will be able to provide customers with access to an expanded range of academic content.
Beginning in 2013, libraries and research institutes will be able to rent access to some 11,000 e-books, 250 journals, and over 15 million database entries. At the end of the rental period, paid fees can be applied to content purchase.
