The specialized library offers a unique composition of sources, literature and information concerning Max Weber, including his intellectual and personal environment. Along with the Max Weber Complete Edition editorial work, the library's collection has been enlarged and systematically refined. At first resource tools like bibliographies, databases or complete indices were developed to support the editorial work. They have become valuable scientific tools of great interest to Weber researchers. They are available after consulting with us first. Some of them are already being digitally offered here.
