Excellent. Thank you for sharing these resources. I think the defunct New York Tribune is also available in miniature pdf form somewhere on the internet. I have no plans to expand my posts beyond the Times, Harper’s Weekly and excerpts from various volumes. I have no more spare time. So posts like yours are invaluable.
Years ago I started looking at old newspapers on microfilm in university libraries. That resulted in one of my few FR threads which can be found at the following link:
Link to reactions to Lincoln's first inaugural speech
It is much easier these days to find newspapers online than it was back when I was spending hours in libraries looking at microfilm rolls of Civil War newspapers.
