The database contains images of seal impressions held in the Estonian National Archives and original seals preserved in the Tallinn City Archives. The collection in the National Archives largely comprises copies of Livonian seals found in various archives by Robert von Toll (1802–1876). The seals in the Tallinn City Archives encompass registers I–III of charters from the former Tallinn City Council archive. The existing descriptions were prepared by Tiiu Oja and Ursula Benninghoven, with additional contributions by Juhan Kreem.
