Process management is an important tool to manage this challenge.The Zurich University of Applied Sciences currently has currently 8 libraries of different departments, which are spread over 3 locations: 5 libraries in Winterthur, 2 in Zurich and one in Wädenswil. In the autumn of 2014, the 2 Zurich libraries will move together with a further University in a new location. In Winterthur, Switzerland, a new, common library for 5 departements will open the same time. The article describes the background and the previous history of the initiated process management, the results obtained and the way forward.
