The division of Germany following World War II had a range of consequences,both for the population of the country and for its institutions, including the Leipzig-based Deutsche Bucherei (German Library). As far back as November1946, two and a half years before the founding of the two German states, it wasgiven a western counterpart in the second largest German publishing centre,Frankfurt am Main. This institution was named the Deutsche Bibliothek(which also means German library).The two separate German states have since become history, and mostof the authorities, organisations and public institutions were unified after 1990. But it was planned that the German National Library maintain its twobuildings, in Leipzig and Frankfurt am Main, while at the same time mergingto become one institution. The Federal Government emphasised the integratingnature of this decision for the newly united Germany: East and Westwould work closely together while each location would still maintain its status.In addition, there was the advantage of being able to maintain anddevelop a main focus for each of the two libraries. Similarly, the old and newtasks could be allocated and modified to suit the respective locations.
