H. P. Karr's Lexikon der deutschen Krimi-Autoren: Internet-Edition is a German-language bio-bibliography of over 120 German-speaking writers of mystery and detective fiction. The database includes information on film, radio and television authors, as well as those writing in more traditional forms. It aims to give the first complete overview of crime literature in German, including authors from both the old and the new German states, as well as those from other countries writing in German. The database was originally published electronically in 1992. For this web-based version there have been more-or-less annual updates from 1998 onward.
