Correction to: The Néron–Severi group of a proper seminormal complex variety (Mathematische Zeitschrift, (2009), 261, 2, (261-276), 10.1007/s00209-008-0324-7)

In the paper [1] referred to in the title, the proof of Lemma 11 is not correct. The geometric observation on face maps, given in the last paragraph of the proof there, does not suffice to give the claimed splitting of complexes in (20). We are unsure if Lemma 11, as stated, is correct.
