In its role as the German National Library for all areas of engineering as well as architecture, chemistry, information technology, mathematics and physics the TIB has spent decades successfully meeting the challenge of being an innovative and competent information provider. On the basis of its superb holdings, the TIB today ranks as one of the world's largest specialist libraries, and one of the most efficient document suppliers in its subject areas.
The TIB recognized the increasing role and importanace of research data for the communication of scientific results early. In 2005, the TIB became a non-commercial DOI registration agency for research data sets from the fields of technology/science and medicine
The registration is always carried out in co-operation with so-called "data centres", institutions that are also responsible for quality assurance and for maintaining and storing the contents.
