Sustainable museum work thrives on the continuous engagement with the objects in the collection. They provide answers to a variety of questions—provided they are preserved over the long term. The foundation for this task is well-planned museum storage facilities. Here, a large part of the museum collections is stored, often unnoticed by the public and usually accessible only to specialists. The storage facilities thus serve as an indispensable pool of materials and knowledge for current and future research, exhibition, and educational work. A professionally managed museum storage protects the collection from damage, whether mechanical, due to unsuitable climate, pollution, light, microbial infestation, insects, or disasters. The storage must be organized in a way that ensures an overview of the inventory at all times and allows for easy access to it.
