Two years ago one of the fee-based websites that has digital images of newspapers had images of my hometown newspaper for the year in which I was born. I am absolutely certain of it. I downloaded a copy of my birth announcement, my grandfather’s obituary, and my great-grandfather’s obituary.
Two days ago, I went back to search for another item from that same time period. The newspapers were not there.
Always search and download when you can. You never know when that website may no longer have the database you need.
Or that you simply can’t find that item that it took you hours to locate.
