Comprehensive online research across museum databases, auction records, and scholarly sources has yielded significant new information about Drost's oeuvre. Key findings include confirmed dimensions and provenance from the Louvre and Metropolitan Museum, new attributed works from UK collections, and conservation details revealing that "The Sibyl" was painted over an earlier composition.
