"Explore the many facets of agricultural life firsthand from diverse populations across more than 30 U.S. states in our new exhibit, Stories of the Land. This collection features over 70 public radio and television programs broadcast from 1954 to 2019, complete with an interactive map to search for stories by location and topic."

There are 108 recordings in all, including "Divided we plow" (1957), "Death of a Small Farm" (1967), a Black experimental farm in North Carolina (1970), Texas Farm Workers (1977), three farmers in Wisconsin (1978), rural and urban Minnesota differences (1990), a Wyoming ranch family (1994), and dozens more.

I really like the interactive map, too. You can click on any single item (I suggest enlarging the map first) to learn about each of the stories covered in the collection. I would consider using the map as an introductory activity in which students could explore a certain part of the country and report what they've learned and how it relates to the big picture of Stories of the Land in America. You could also project the map full screen and have students choose one story with a personal connection either to the place they live now, the place their ancestors lived, or a place they're simply curious about.
