Internal classification and reconstruction
In the 1950s, reconstructive work began to be done on individual Oto-Manguean language groups. Proto-Oto-Pamean was reconstructed by Doris Bartholomew, Proto-Zapotecan by Morris Swadesh, and Proto-Chiapanec–Mangue by Fernández de Miranda and Roberto Weitlaner. The classification by Campbell (1997) was the first to present a unified view of the Oto-Manguean languages. In 1981, William Merrifield published a reconstruction of the kinship terminologies of each of the Oto-Manguean branches and of Proto-Oto-Manguean. Unpublished reconstructions of Proto-Oto-Manguean grammar have also been made by Terrence Kaufman.
