Books that help to refute Sedavacantists and other schismatic traditional groups

I wanted to start this tread on discussing and posting peoples ideas and experiences with schismatic traditional groups. Especially with an emphasis on books for apologetics.

These are two of the best books that I have found and possess that help to refute the arguments of the Society of Saint Pius X and Sedevacantists.

1. More Catholic Than the Pope: An Inside Look at Extreme Traditionalism by Patrick Madrid and Pete Vere

2. The Pope, The Council, and the Mass: Answers to Questions the "Traditionalists" Have Asked by James Likoudis and Kenneth D. Whitehead

Hope this helps any in need of material like this, God Bless+
