Kritisches Lexikon zur deutschsprachigen Gegenwartsliteratur (KLG) is a guide to contemporary German-language authors. For each author, it offers a biography, a bibliography of his or her works, and a bibliography of articles and books about the author.
Yes, it's print, but it's well worth your time because it's a very useful resource!
