"It’s known as the Deep Backfile project. A team of Penn Libraries staff has been analyzing an accumulated history of periodicals in the collection—journals, magazines, newspapers, academic journals, comic books—to determine which are no longer restricted by copyright and are therefore available for free and unrestricted use. “That sort of information is a gold mine for researchers of all sorts,” says John Mark Ockerbloom, leader of the project. He writes the Everybody’s Libraries blog and is known for his knowledge on copyright, having researched the topic starting as a graduate student in the 1990s. ...
Deep Backfile is focused on serials, a library science term for any kind of continuing publication published in parts, issues, or volumes.

Many of them, including ones from popular subscription packages, did not maintain their copyrights but need to be researched to confirm that.

A few years ago, the Libraries created a complete inventory of serials published before 1950 that did have renewed copyrights, which led to Ockerbloom deciding to investigate which did not have those renewals. He created information tables for different sets of serials, including some popular subscription packages, which are the basis for Deep Backfile. All told, the Deep Backfile project is researching more than 10,000 such serials...."
