Visitors can enter two portals, “Introducing the Reformation” and “Resources for Deeper Study.” Each provides a range of information in a variety of formats. For example, the “Introducing …” portal includes a Martin Luther biography, an interactive timeline that shows how the movement progressed, and a slideshow of other key figures such as Hus, Zwingli, and Calvin. A multiple choice quiz challenges readers to match reformers with their quotes. There are book recommendations including a collection of primary source material and commentary. The “…Deeper Study” page links to a 30-minute documentary on Katie Luther, giving a glimpse into Luther’s domestic life and showing Mrs. Luther’s unique contributions. This is a go-to site for leaders charged with helping their congregations observe the 2017 anniversary, and for anyone wishing a deeper understanding of the historic Protestant-Catholic divide. The material is appropriate for youth and adults and it is available at no cost.
