There are plenty of books available in Logos about Schillebeeckx, but nothing by him.
How about getting The Collected Works of Edward Schillebeeckx (T&T Clark, 2018)? A bundle of his collected works was apparently in pre-pub back in 2013 but was pulled (see this thread). However this must be a newer edition of it.
