The Partnership for Progress on the Digital Divide (PPDD) is a not-for-profit organization that brings together a diverse and multidisciplinary array of individuals and organizations, connecting academic research to policymaking and practice to forward progress on the digital divide and related challenges. PPDD convenes researchers, practitioners, and policymakers at a series of biennial international conferences, yielding high-quality interdisciplinary collaboration and scholarship that highlights new solutions to longstanding problems of great social significance and explores emerging contours of the digital divide. This special issue features eight selected papers from the PPDD conferences in 2015 (Scottsdale, Arizona) and 2017 (San Diego, California) to address the intersection of the digital divide and social justice.
