Imagine how much Black American (descendants of slaves) history has been lost to time because of mindsets like this. Tragic too because they built this country, yet the full extent of their contributions will never be known.
Never indicted that. Dorsey collection and 19th century travels aside, how would you say a Black person in early 17th century America should've preserved their history/life experiences in recordable format and passed it to offspring they may or may not have been separated (i.e., sold) from?
Your point? "Free" Blacks were exceptions (about 9% by 1850) not the rule. Preservation of their history too was an exception, not the rule. Controlling for literacy rates and economic deprivation suppresses the preservation percentage more.
Besides, 9% of 4 million is 360,000. Quite a lot of people.
On February 25, 1837, Cheyney University of Pennsylvania became the nation's first Historically Black College and University (HBCU). -- Google
The nature of slavery and the operational structure of this nation ensured that significant quantities of Black history was lost (original premise).
Quite a bit of the history of the 19th century in America was originally in the form of letters.
I've preserved scrapbooks this way - it's simple, fast, cheap, and it works. Yes, you can read all the text in the photos.
Then this photo archive can be put online for researchers and anyone interested.
The one I use also uploads the end result to a cloud service of your choice.
Fragile documents and especially books don't fare well on scanners.
