The Annotated Luther series
I did not find individual introductions to these Luther writings to be universally helpful. I really appreciated the illustrations throughout and the end indicies, particularly the Index of Names. That index alone is an improvement missing from some volumes of Luther's Works.
For an LCMS Lutheran, I find this annotated edition of the Large Catechism to be problematic. Why? Simply put, the annotator could have confessed salvation in Christ alone while annotating what I know as "paragraph 66" and clearly avoid universalism (Note 190; cf: https://www.cph.org/p-670-one-true-god-understanding-the-large-catechism-ii-66.aspx). The strength or weakness of these volumes is dependent on the confession and contribution of each individual volume and writing editor. Note 7 on catechetical preaching on Ember Days was helpful and insightful, as was note 32 on the Divine Office. Notes 11 and 12 on Luther and Zwingli's interaction on the Lord's Supper could be clearer. (My numbering is based on the kindle review copy version.)
This is a unique volume with seventeen essays by German, Swedish, Finnish, Australian, and American contributors. Among the Americans, most are LCMS. One, Paulson, is ELCA.
Originally published in 1992, this is a masterful work of historical theology. Author Kiecker ably demonstrates the need for reform in the Church, attempts at reform, focuses on Luther's time and opportunity, what the Lord accomplished through Dr. Luther, other reformers and their approaches, and challenges since Luther.
Honestly, I haven't resonated with all publicity related to this title. I understand where "Throw out all those notions..." was going, but my members read that and were more suspicious about this book.
