Floppy disks were introduced in the early 1970s and in the two decades before they became obsolete, tens of billions were produced, most of which ended up in landfills, long-forgotten storage, or libraries. Archivist Leontien Talboom has been working for the past few years to preserve the floppy disks in the Cambridge University Library, collaborating with retro-computing enthusiasts. She talked to @PopularScience about the project.
