Out of 175 American Indian languages, only about 20 are being taught to children as generations of Indians die off and leave little or no evidence of their languages or cultures.

"This is probably the hottest topic in linguistics right now," said Lyle Campbell, director of the University of Utah's Center for American Indian Languages (CAIL). "The languages are becoming extinct at such an accelerated rate.

"This is a worldwide problem," Campbell added. "All of the Utah (Indian) languages are in trouble."

It's a big enough problem that the Smithsonian Institution in Washington, D.C., has decided to partner with the U. center in an effort to record and archive Indian languages, stories and cultural histories in video, audio and book form.

When languages are lost, Campbell said, "then we're all diminished, because we don't have access to their experiences."

One of the U.'s current projects, funded by an ongoing grant, involves the preservation of endangered languages in northern Argentina and Brazil.

The Smithsonian is lending its support to the U. center with the use of linguists and anthropologists.

"They have very similar interests to ours, so it was a natural collaboration," Campbell said. "We'll be able to get more people involved — we need more human resources."

Unique collections of endangered languages are kept in the National Anthropological Archives, which is housed in the National Museum of Natural History.

Within that museum is the Department of Anthropology's senior linguist, Ives Goddard, who said the department's staff has made the study of Native American languages a priority for over 150 years.

The one-of-a-kind arrangement with the U. will have students traveling to Washington to work with Smithsonian collections and staff.

"We realized that we were both thinking along the same lines after the appointment of Lyle Campbell to head CAIL last year," Goddard said.

After two meetings in Washington, the two sides drew up a declaration of shared interests and goals. The Smithsonian partnership will be housed in the same building at Fort Douglas on the U. campus where U. professor of linguistics Mauricio J. Mixco has been working on a language preservation project, funded by the National Science Foundation.

Mixco is part of four teams sifting through 120 audio tapes filled with interviews, stories and anecdotes from members of the Shoshone tribe. The recordings date back to the 1960s and 1970s, when anthropological linguist Wick R. Miller ventured onto reservations with a curiosity and a tape recorder. Miller left the tapes behind as part of his estate.
