The Metropol-Card permits the use of 29 different municipal libraries across the Rhine-Neckar Metropolitan Region. Orginally the project involved a common library card for the libraries in Ludwigshafen and Mannheim, but in 2012 the project was expanded to other municipal libraries in the states of Hessen, Rhineland Palatinate and Baden-Württemberg. A total of 1.7 million books and other media are now available at 80 different lending locations. The annual fee for the Metropol-Card is 20 euros. For further information, see www.metropol-card.net.
