I've just discovered that Brendan G Carroll's definitive biography of Korngold, The Last Prodigy, is out of print. As next year is the 50th anniversary of EWK's death and there is going to be A LOT going on to mark the occasion, it seems completely ridiculous that this book, which took Brendan 25 years to write, should be unavailable. It's an invaluable and irreplaceable resource. The Korngold website, run from Athens by another devoted Korngold fan, Eleftherios Neroulias, is carrying an online petition to the publisher, Amadeus Press, begging for the reprint of the book. You can read and sign the petition here.
My own rather more modest book still seems to be in print, but it's no substitute and I am the first to admit that.
