Geisler, Norman L., and Ralph E. MacKenzie. Roman Catholics and Evangelicals: Agreements and Differences. Grand Rapids, MI: Baker, 1995.
This book by Geisler and MacKenzie is a terrific explanation of the differences between Catholics and Evangelicals. Chapters 9 and following explain the differences between the views, and they offer a defense of the Evangelical understanding.
White, James R. The Roman Catholic Controversy. Minneapolis, MN: Bethany House, 1996.
James White is perhaps the most qualified Protestant scholar on the subject of Catholicism alive today. He has written many books on the subject, but we only consulted this one, which we found excellent. We would consider it the best book that we read on the subject. White has debated various Catholic apologists on this subject over the years, and his public debates are worth listening to.
McCarthy, James G. The Gospel According to Rome. Eugene, Or.: Harvest House, 1995.
McCarthy has the most extensive catalogue of citations from the Catholic Catechism of any book that we researched on the topic.

Dennis McCallum “Roman Catholicism” McCallum’s article isn’t so much an apologetic work against Catholic doctrine, so much as an accurate explanation of what Roman Catholicism teaches.

Kreeft, Peter, and Ronald K. Tacelli. Handbook of Catholic Apologetics: Reasoned Answers to Questions of Faith. San Francisco: Ignatius, 2009.
Kreeft and Tacelli’s book is mostly focused on general Christian apologetics (e.g. comsmology, design, historicity, etc.), but the last chapter focuses on Catholic apologetics (e.g. Mary, purgatory, teaching magisterium, etc.).
Hahn, Scott, and Kimberly Hahn. Rome Sweet Home: Our Journey to Catholicism. San Francisco: Ignatius, 1993.
This book is coauthored by Scott and Kimberly Hahn. It is told from both of their perspectives, as they slowly converted from Protestantism to become leading Catholic apologists.
