Society-AYMARA
The Aymara Indians are located mainly on the Bolivian and Peruvian
altiplano, centering about Lake Titicaca. Their Peruvian distribution
gradually contracted because of the expansion of the Quechua Indians,
especially, but not exclusively, during the time of the Incan Empire.
Other peoples found within the Aymara area include isolated remnants
of the formerly widespread Uru and Chipaya Indians (cf. Tschopik 1946:
502; La Barre 1948: 33; also cf. Vellard 1959-60).
Linguistically, Greenberg classifies Aymara with Quechua as a separate
group within the Andean subfamily of the Andean-Equatorial language
family. The Aymara language may be divided into a number of local
dialects. The Uru-Chipaya are linguistically distinct from the Aymara
and belong to a separate subfamily of the Andean-Equatorial family
(Steward and Faron 1959: 22-23; Voegelin and Voegelin 1965: 77-81).

This should help with search, at least now you know where to look.
Aymara and quechua are the two major native languages spoken in Bolivia.
