De acordo com o wiki , ele é incluído no Return of the King.
The Lord of the Rings Appendices were published in The Return of the King and were the reason that the release of the book was delayed.
Além disso, eles devem estar completos nas edições em inglês, além de uma versão em um volume específica e suas reimpressões de booklets.
In 1968 Allen and Unwin published a one volume paperback edition, including only Appendix A I v, ‘The Tale of Aragorn and Arwen’. Apparently this was done because a paperback thick enough to include all Appendices could not be produced economically. Tolkien agreed, but he made a special plea to include The Tale of Aragorn and Arwen.[10] This is the only edition in English (several print runs of which were issued hardbound as book club editions) known not to include the complete Appendices.
