We are proud to partner with some of the largest regional and national library groups in Europe, Middle East and Africa to provide infrastructure that supports library collaboration, and facilitates their operations at a regional and national level.

Our mission to connect the world’s libraries has never been so relevant given the web-driven information environment we live in today.  Library users have changed their patterns of behaviour when it comes to information-seeking and libraries are changing with them.  OCLC’s global enterprise strategy to collaboratively build Webscale with libraries provides an approach and solutions for libraries to increase the collective reach of their collections, while driving efficiencies in collection management across electronic, digital and physical materials.
