Bits and pieces of my 2001 PhD. dissertation are incorporated into the book, and in the few places where the dissertation contains a more detailed discussion there is a note to that effect, but the overall project has changed and expanded so much over the past ten years that I consider the dissertation to have been superseded in almost every respect. However, the two appendices contain concentrated information that is not available in the book, so I am making them available (unrevised) as supplements here.
Appendix A: The Nihon shoki on Writing's Introduction and Development
Appendix B: Notes on the So-called 'Remnant Texts of the Suiko Court'
