Recently I purchased Flannery's Vatican II collection from Logos. It is a great resource. Unfortunately, other Verbum/Logos resources don't link to Flannery's collection. One solution would be to "fix" Flannery. But then I realized that there already is a better - and easier - solution. Redo Flannery.
So, my suggestion is that Verbum put out an updated Vatican II Collection, using Flannery as a model. Have the sixteen conciliar documents and all the major Church documents since then under each of those sixteen categories, right up to the present day. The beauty of this solution is that Verbum already has most of these documents offered in other collections. Very little work would be required on their end! All the links would be there already! It could be like a "greatest hits" collection (so to speak) for those who can't afford to buy all the collections of official documents now offered. And, what a great way to celebrate the 50th anniversary of the Council!
