(AP) — About 35 years worth of TV news that was faithfully taped by a Philadelphia woman will now be archived in an online library.

When Marion Stokes died last year, she left behind about 140,000 video cassettes totaling about a million hours of newscasts.

Stokes' son tells The Philadelphia Inquirer (http://bit.ly/1ksefVO ) that his mother felt she had a mission. He says she resisted suggestions that recording the shows was a waste of time.

Stokes had several VCRs running simultaneously 24 hours a day. She taped cable channels as well as local news in Philadelphia and Boston, where she spent part of her life.

On Tuesday, the tapes are scheduled to arrive at the Internet Archive in California, where they will be digitized.

The story was first reported by Fast Company magazine.
