This grant supports the Digital Public Library of America to expand its nationwide service hub network. Service hubs are on-ramps in each state for uploading and sharing digital content from the smallest private collection in a remote rural library to the largest state library or museum. As such, they are the key to DPLA's grass-roots, bottom-up, decentralized approach to building a national digital library. Hubs host locally provided digital content for the DPLA, correct and add metadata to uploaded items, coordinate local events and public outreach, and collaborate with state cultural institutions on digital initiatives. Grant funds will allow the DPLA to add eight new service hubs to its current roster of 15, increasing coverage by 50 percent and moving the institution closer to its goal of being a truly national digital library. Funds from this grant also support a DPLA initiative to partner with authors, publishers, libraries, and the White House to launch a new service network that provides free eBooks to children.
