What is the project? Who are the authors or contributors? What are their areas of expertise?
North American Slave Narratives is a collection of books, articles, pamphlets, and broadsides that collectively tell the story of “the African American struggle for freedom and human rights in the eighteenth, nineteenth and early twentieth centuries.”  This makes up a massive collection and time frame held by the University Library at the University of North Carolina at Chapel Hill.  There are a group of librarians and professors who are in charge of making selections to the collection.

What is the data source or sources? Is the data aggregated or extracted from several different places, or did they use a historical dataset? Is the project clear about how data were accessed, organized, and/or manipulated for analysis?
This data set is made up of several types of documents as mentioned above.  There is no explanation for any type of requirements for being included in the collection, other than a mention of a group that does the selecting of the pieces.

Is the data available for download anywhere? If no, is there a reason provided (copyright, privacy, etc)?
The data is freely available for download through the “Documenting the American South” site, going to the “collections” tab and finding the collection called “North American Slave Narratives.” It is also linked HERE.  The last link on the page, “Download full text of this Collection” immediately begins the download of the full dataset used for the collection.
