by Peter Kurilecz Since 2010, the Library of Congress has been collecting every single tweet published on Twitter. The idea was to create a comprehensive public archive of the social media platform for researchers to comb through and to study. But that was all easier said than done. More than half a billion tweets are sent every day, a staggering amount of information to catalog even for one of the world's biggest libraries. And yesterday the library announced that it would scale back its Twitter collection considerably and will now archive tweets on a very selective basis. Professor Michael Zimmer of the University of Wisconsin-Milwaukee has written about the challenges of storing this never-ending stream of social media data, and he joins us now. Welcome to the program. https://urldefense.proofpoint.com/v2/url?u=http-3A__n.pr_2Cj4D3e&d=DwIFaQ&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=b5NZPQUb9_r2rQ3Zd74ATT3aSs9yKyRnJLOhqJvd7fE&m=O0J5Gez9JvGs5CJynEMAWFz54ry0fbyZeyqTei1jJ2I&s=3zZRRzlCx5FAlvCmakVC3W6gM7zDlJZxLalH5zowY80&e= https://urldefense.proofpoint.com/v2/url?u=http-3A__n.pr_2Cj4D3e-2B&d=DwIFaQ&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=b5NZPQUb9_r2rQ3Zd74ATT3aSs9yKyRnJLOhqJvd7fE&m=O0J5Gez9JvGs5CJynEMAWFz54ry0fbyZeyqTei1jJ2I&s=8zVzwezu-usf1ziRsK0oWQzd8umbAuyUo0OMGP8Ci_A&e= --
