   • 1991: Christopher Seeley, A History of Writing in Japan

     Later—during the ninth century—the kō and otsu groups did come to be used interchangeably.

   • 2001: John R. Bentley, A Descriptive Grammar of Early Old Japanese Prose

     He rejects the claim of Matsumoto (1984) that the kô and otsu -o- vowels are in complementary distribution, and therefore these two vowels are allophones of a single vowel.
