Thanks to state libraries, special collections, museums, and historical societies, and also to genealogists and local history buffs, some newspaper content in the public domain that used to exist only on microform has been uploaded to the web and made available.
These are often, but not always, topically specific collections of articles rather than a chronological sequence of entire newspapers.
The old fashioned and still incredibly useful way to get old newspapers is to go to a local library and look it up on microfilm or microfiche (slightly different kinds of microform machine.)
These machines enlarge tiny scans of the original back to readable size, and you can usually print off pages. They are rarely indexed except for the title of the newspaper and the date. So you need to know what you're looking for or be prepared to skim a lot.
Search the web archives of newspapers with a long history for article titles, click them, and get the exact date to look for. Search on the web for newspaper title keywords year to get started. For example, New York Times shipping san francisco 1959. Only major national newspapers will be indexed online - smaller ones can't afford to do it.
Always call ahead if you want to use microform because the person who knows how to use the machine will have to set it up and instruct you.
