Ivo Vogel and Elisabeth Schrecklinger, both of Staatsbibliothek zu Berlin, have published Retrospective Digitisation of Legal Sources in Germany, Legal Information Management, 14, 105-109 (2014).
Here is the abstract:
This article … deals with the efforts of German libraries to digitise historical legal sources and make them publicly available. Although the main focus is on two selected libraries, a general overview is included. Commercial products are not considered since their contents are likely to become increasingly less relevant due to German law libraries’ own initiatives. More attention is paid to problems that have been identified during the implementation of digitisation projects such as the recording of full texts is highlighted. The retrieval of digitised legal materials and, eventually, the digitisation of historical legal gazettes or parliamentary literature is also discussed. This contribution focuses exclusively on the retrospective digitisation of historical legal materials.
