Qwyrxian you were quite objective in your point but may not be so in your point except US and UK nautical charts that you mentioned and Oda Mari provided the links in the NPOV side above As saying international almanacs  all without exception use Senkaku Islands this is wrong The documentary year book with which I found that Diaoyu Islands but no Senkaku Islands was used by SG of the UN in his official letter is an international almanac named International Organizations and the Law of the Sea Documentary Yearbook  of NILOS Documentary Yearbook It is for collection of related documents from the United Nations system Therefore this is a very high if not the highest quality of year book or almanac Another UN document a UN General Assembly document can be found in page  of this year book which mentioned D and S as followsSince the s China and Japan have continued to dispute sovereignty over a group of five islets and barren rocks known in Japan as Senkaku and in China as Diaoyu  And for encyclopedias I checked Britannica neither Senkaku Islands nor Diaoyu Islands can be found  When you asserted all Encyclopedias all almanacs can you list all of them you checked Please dont do cherrypicking Dont assert too much more than what you actually did Bobthefish ever gave a search result on Library of Congress I rechecked it and am sure it is correct  note Bobthefish has been topic banned for a year due to Decorum issue but it does not mean that the objective contents he used before cannot be used by us So your point can be used by us to reach certain consensus Your point is biased and it asserted too much more than reality and objectivity
