Just curious what others think for books which best describe The Crisis.  My favorite is Against the Heresies by Lefebvre as it goes point-by-point through the errors and shows how they've all been embraced.  Any other good ones?

I remember reading the volume from when +Fellay became the Superior General and +Williamson noted that that went against the Statutes of the Society - that one of the bishops be the Superior General.  He figured it would be fine but, unfortunately, history shows this hasn't been the case.  Interesting reads from those days.

If you want to access Open Letter to Confused Catholics by Archbishop Lefebvre, the above link now tries to take you to the new SSPX site. Before being navigated away to the new site, click on 'Library of Catholic Docuмents' and then on 'Archbishop Lefebvre' and you will find the book.

Father Feeney’s writings laid out the true doctrinal root cause of the Crisis as it was actually happening, and not via the hindsight of the post Vatican II era.  Everyone else applied the 20/20 vision of hindsight.  Father Feeney therefore wins hands down.

Heck, 98% of Trads STILL don’t get it.  Archbishop Lefebvre himself promoted “Anonymous Catholic” soteriology.

A tentative submission (because I just found it and haven't read it yet):
 The Mouth of the Lion 
Bishop Antonio de Castro Mayer & the Last Catholic Diocese
by Dr David Allen White

It looks like a good one for this thread.

A lot of the Michael Davies books give a good picture of the crisis.  Some, like the Liturgical Revolution series, deal with specific things like the Council, the New Mass etc.  The Apologia series, although it deals specifically with Archbishop Lefebvre, give a good snapshot of what was going on at the time (all of which is still relevant today) — all the chaos & destruction in the parishes, and the contrast between that destruction — the authorities in the Church supporting all sorts of non-Catholic stuff — vs. suppressing Catholic doctrine & practice.  So if someone wanted something more anecdotal than doctrinal, I think they're very worthwhile.  Especially the Apologia Pro Marcel Lefebvre series. And one would not have to read all three books to get the idea.  Volume I would do.

My link to the Apologia books online, above, seems to redirect, so let me try another way:
