The plan is to continue the edition of the "Liv-, est- und kurländisches Urkundenbuch" that was published in two divisions in 15 volumes until 1914. For it has not been possible to continue the publication since then, the gap between those two divisions for the years 1472 to 1494 remains. This gap should be closed with this new edition. Volume number 13 and 14, comprising the years 1472-1483 will be edited. They will contain together about 1500 items.
