The AAPB mission is a collaboration between the Library of Congress and GBH to digitally preserve significant public radio and television programming from the last 70 years, with over 124,000 items archived. The document highlights the importance of preserving magnetic media, which has a limited lifespan, and outlines the fix it+ platform for crowdsourcing transcript editing to enhance accessibility and metadata.
