Konkordienbuch
Notable among Kolb's numerous publications is the 2000 edition of The Book of Concord, which he edited along with Timothy J. Wengert. Its publication was hailed "a historic moment" by some, although others questioned the edition's use of the September 1531 octave edition of the Augsburg Confession rather than the earlier quarto edition, which has been used in all other editions of the Book of Concord.
