April 2009 | 2 DDC in Germany – a short history no nationwide standard and no central bibliographical service in the field of classification 1998: Working Group on Classification founded 2000: feasibility study for the introduction of Dewey in Germany interests: library networks/larger university libraries: offer access to cataloguing data with Dewey numbers which are often transferred from the LC or from the BL German National Library: offers subject access to national as well as to international libraries and users

| Dewey goes Europe, ÖNB Wien, 28. April 2009 | 3 Main points of criticism DDC was considered to represent the state of the scientific and technical knowledge in the late 19 th century the scheme was identified with a White Anglo-Saxon Protestant point of view deficits in fields like German and European law different viewpoints of the academic tradition and organisation of subjects centralised and strict management and the legal and economic organisation strong copyright restrictions high fees for licensing

| Dewey goes Europe, ÖNB Wien, 28. April 2009 | 10 Working with Dewey shows number building needs a lot of time very error-prone process impossible to control the number building process rules: are too complicated it’s too difficult to find the respective instruction notations are not deep enough and cannot describe the document’s content precisely enough support: it’s helpful to discuss individual cases with experienced classifiers it’s not helpful to research the practice of other libraries we acknowledge the work of the editors and their effort to improve the DDC

| Dewey goes Europe, ÖNB Wien, 28. April 2009 | 11 Other ways of using Dewey organisation of subject information services (portals, virtual libraries or other presentations available in the web) not using Dewey in detail avoiding the process of number building using the second or third Summary using Dewey on a “medium level” gradually, several variations of using Dewey emerge
