"1,615,000 Old Upstate, Western & Central NY Newspapers" may be searched on a site rather deceptively called
Old Fulton NY Post Cards. Since 1,615,000 newspapers would come to about 155 issues per week for the last 200 years, I'm pretty sure that 1,615,000
pages is meant—still a remarkable accomplishment. The site's use of frames is stifling, but the search engine works well enough, and the pages are rendered as legible PDF files.
