Dana L. Robert’s volume offers an excellent introduction to the achievements and challenges in writing African Christians history over and against the various failings of the missionary archive. It is based on a 2015 conference celebrating twenty years of the Dictionary of African Christian Biography (DACB, www.dacb.org), which since its foundation by Jonathan Bonk has grown into an important nonproprietary and crowd-sourced archive of African Christian biographies. As Bonk himself tells us in this book, the free availability of the DACB (including publication rights) has guaranteed the wide circulation of its now over 2,200 biographies, with Nigeria and South Africa topping the list of online users (together almost forty percent of total access traffic). This is a truly impressive achievement, and I highly recommend this jublilee volume as an accompanying text to the DACB.
