Presentation given by Virginia Danielsson from NYU Abu Dhabi. The session was part of the Library Day during ADIBF2015 and included in the ADIBF Academy Certificate Expert Librarian. Arabic Collections Online (ACO) is a publicly available digital library of public domain Arabic language content. Funded by New York University Abu Dhabi, this mass digitisation project aims to expose up to 15,000 volumes from NYU and partner institutions over a period of five years. NYU and the partner institutions are contributing all types of material — literature, business, science, and more — from their Arabic language collections. ACO will provide digital access to printed books drawn from rich Arabic collections of prominent libraries.
