This study presents a historical view of Eucharistic concelebration, the unity of every priest in the one priesthood of Jesus Christ, and theological and pastoral considerations for concelebrants.
An excellent treatment of the issue of concelebration, providing an overview of all known historical incidents and an account of the discussions that happened at Vatican II. I don't think this book will convince someone one way or the other on concelebration, but for those who do it regularly, it sheds some light on what is actually happening.
