(*) The February 1966 US paperback revised edition is the earliest edition whose text ("1966-A") incorporates a version of the revision Tolkien prepared in 1965, the last that he prepared. Slightly different versions of the same revision were incorporated in other editions and all of them introduced new typesetting errors. --The Annotated Hobbit (1st ed., 1988), Appendix A
