The Tenth Edition of the Britannica in fact has two alphabets of articles (one a reprint of the Ninth Edition, the other a supplement); the Anglo-American Encyclopedia merged these into one alphabet. One of the two parts of the Britannica also breaks at UPS. The other meanings of UR are not additional articles in the 11th, but they can be found in the index.
