Dan, I have full access both to www.newspapers.com and www.newspaperarchive.com. Most well-known Afro-American papers are included.
I've devoted thousands of hours to perusing through these online archives, launching any type of imaginable search. So let me know if I can help.
Please find attached an appetizer. Image quality of the scans is not the best for most of these archives. It is ok for text, but most often images are unusable.
