The Harvard Divinity School held a conference in 2005 addressing global Pentecostalism in the black community. HDS' site provides video feeds of the three panels featuring leading voices talking about global Pentecostalism, African-American Pentecostalism, and the future of this movement.
Published by the Assemblies of God USA, the Enrichment Journal site features articles by historians — including Cecil Robeck — and theologians discussing the legacy and impact of the Azusa Street mission and William Seymour. Also, several eyewitness accounts make for interesting reading.
Robeck is a professor of Church History and Ecumenics at Fuller Theological Seminary and a historian of Pentecostal tradition. He is the author of The Azusa Street Mission & Revival: The Birth of the Global Pentecostal Movement.
