The above map is part of an old Korean map in an atlas entitled "Yeojido" (輿地圖), which is part of the Korean Map Collection at the University of Wisconsin at Milwaukee. The map, which is believed to have been made between 1800 and 1887, shows the Korean island of "Ul-lungto" (菀陵島) and a neighboring island labeled "U San do" (于山島). The description of the map, however, lists the islands as "Ullung Do" and "Dok do," even though Dokdo (Liancourt Rocks) does not appear on the map. Notice that the description of the map was "created" on October 7, 2009.
Usando (于山島 - 우산도) was the old Korean name for Ulleungdo's neighboring island of Jukdo (竹島 - 죽도), which is Ulleungdo's largest neighboring island and only about two kilometers off Ulleungdo's east shore. Koreans, however, claim that Usando was the old Korean name for Liancourt Rocks (Dokdo / Takeshima), but have no maps or documents to back up the claim. Liancourt Rocks is essentially two rock islets, not one, about ninety kilometers southeast of Ulleungdo. Korea's old maps and documents show that Usando was Ulleungdo's neighboring island of Jukdo, not Liancourt Rocks (Dokdo / Takeshima).
It is extremely disappointing to see that the people at the University of Wisconsin at Milwaukee have allowed "Dokdo" advocates to misrepresent the Korean map on the University's Web site. I hope the university quickly corrects the error and is more diligent in the future in guarding against the antics of Korea's "Dokdo" advocates.
