Dr. Bognár Éva, an economist and Zsolt Csalog's widow, died in 2015. After Csalog’s death (1997), she inherited his collection. In the early years of the new millennium, the National Széchényi Library purchased the collection, though some parts of it remained with her (manuscripts, letters, private writings). In 2008, Éva Bognár published one of the last novels by Csalog privately, causing a literary and personal scandal. The author’s children and some of his friends had been against publishing the novel due to its alleged second-rate quality.
