His book Lead Us Not into Temptation: Catholic Priests and the Sexual Abuse of Children (1992) was the first major book on this issue. His 2004 book Vows of Silence deals with the sexual abuse of Marcial Maciel, the founder of the Legion of Christ, and the cover-up of that abuse. The author also adapted Vows of Silence into a film. Berry has been frequently interviewed in national media in the United States, has worked as a consultant for ABC News, and contributed to the National Public Radio and is a speaker on sexual abuse issues and popular culture.
Berry has also written books and news articles on music, particularly jazz, and co-wrote Up from the Cradle of Jazz: New Orleans Music Since World War II with Jonathan Foose and Tad Jones.
