Shortly after the 2006 death of his old friend, famed science-fiction Writer Stanisław Lem, Stiller published a book of reminiscences, Lemie! po co umarłeś? Opowieść w reminiscencjach (Lem, What Did You Die For? A Story in Reminiscences), Kraków, vis-à-vis/etiuda, 2006.
In 2009 Stiller published a 685-page volume of his collected poetry, Poetyka pierwszej dziewiątki (Katowice, Wydawnictwo KOS), which included a CD of his readings of selected poems.
