Black in America: The Paradox of the Color Line


 
At the start of the twentieth century, the pre-eminent black sociologist, W.E.B. DuBois, identified the color line as America's great problem. While the color line is increasingly variegated beyond black and white, and more openly discussed than ever before as more racial and ethnic groups call America home, his words still ring true.
 
Today, post-racial and colorblind ideals dominate the American narrative, obscuring the reality of racism and discrimination

Let me draw you a map: knowledge management from "two completely different streams of thought"

Let me draw you a map: knowledge management from "two completely different streams of thought" HeavyHead, Danielle; Greenshields, Mary This paper represents the results of a conversation between Adrienne Heavy Head, the creator and manager of the Blackfoot Digital Library (BDL), at the University of Lethbridge in Alberta, Canada, and Mary Greenshields, a new librarian in Alberta. The aim of the conversation was for Mary, a settler living in traditional Blackfoot Territory, to learn about the creation and maintenance of the BDL and to gain insight into the organization, access, and classification of information within the library as a real-life example of some of the Protocols suggested by the Canadian Federation of Library Associations. Adrienne and Mary hope that this conversation will help librarians to better understand knowledge management from a Blackfoot perspective and might inspire librarians to start and continue such conversations with the Indigenous peoples upon whose lands their libraries rest.
