This list contains most of the major references to Helmut Lachenmann during the preceding 20 years, as well as his own writings or interviews that he has given, but it is in no way complete. The list is thus divided into two categories, the first of which is arranged chronologically and the second of which is arranged alphabetically and chronologically if the same author has written more than one article on Lachenmann. Most of these texts are in German and have yet to be translated into English. They are here listed for purposes of consultation. His most recent articles, i.e. those written after MaeE was published in 1996, are also listed; where no author is mentioned in the first category, it is Lachenmann.
