The compilation drew on the acquisition file — the auction catalogue entry, the payment receipt, the auction house's condition photographs of the sheet, correspondence with the department specialist, and the New Hollstein catalogue entry for no. 170 — together with a survey of institutional collection records for this plate. What that established is on the object record and the state atlas, with the evidence and confidence for each field. What it did not establish is on the research questions board.\n\nFrom this entry onward every change to the canonical record is logged here with its reason and, where one applies, the name of the person who found it.",
