The new four-volume selection edition is less biographically oriented towards the development of Luther's theology and more focused on the impact achieved by the event of Luther: it highlights his reformative writings in those dimensions that have been consequential for the transformation of the existing church structure and have permanently shaped the establishment of a Protestant church. The text design aims to preserve the original linguistic sound as much as possible, unless Latin writings are translated into High German: the vocabulary, phonetic, and morphological state of the text from the Weimar Luther edition remains unchanged. Careful orthographic modernizations serve as reading aids. The first volume gathers the most important texts regarding the beginning of the Reformation, volume 2 focuses on the Reformation of piety and biblical interpretation, volume 3 addresses church and school, and the last volume.
