In CGP Grey's video "The Race to Win Staten Island", he manages to open old copies of the New York Times for his research (around 1:20).
Where are these available? Can I also get old copies of the New York Times?
The New York Times website has details of where copies can be bought on microfilm and CD-ROM:
