Ernst Krenek is one the composers of 1900 with major importance. At the moment I couldn't find anything from Krenek in IMSLP. Sooo, if you are planning to publish something from Krenek I suggest especially his vocal works: operas (forexample Johnny spielt auf), and lieder.
Personally I am very interested on "Reisebuch aus den österreichischen Alpen" (text by the composer), op. 62 (1929)

Please read our public domain page carefully. Krenek died in 1991, meaning he will not appear on IMSLP for a very, very long time.
