For more than 15 years, the Hamburg State and University Library (SUB) has been digitizing historical collections. By now, more than 50,000 objects have been made available online – e.g. including many special collection, such as music autographs, maps, bequests, photographs, graphics, and handwritten objects. Since 2018, this infrastructure is also used to digitize the collections of other cultural institutions, such as museums or special libraries, in Hamburg. To support research and teaching, the digitized objects are made available under open licenses from Creative Commons. In this coffee lecture, the working unit for Digitization offers you insights in the services and research options. For three million of the five million objects, a full text search is available.
