Lutheran Service Book (LSB) is the newest official hymnal of the Lutheran Church–Missouri Synod (LCMS) and the Lutheran Church–Canada (LCC). It was prepared by the LCMS Commission on Worship and published by Concordia Publishing House, the official publisher of the LCMS. It is the fourth official English-language hymnal of the LCMS published since the synod began transitioning from German to English in the early 1900s. LSB is intended to succeed both The Lutheran Hymnal (TLH) and Lutheran Worship (LW) as the common hymnal of the LCMS. Supplemental and companion editions to the hymnal were released throughout the end of 2006 and into 2007. The hymnal was officially approved by the LCMS at the 2004 LCMS National Convention in St. Louis. It was officially released on September 1, 2006, but many customers who pre-ordered the hymnal received their copies several weeks earlier.
In April 2015, Lutheran Service Book became the first Lutheran hymnal to be made available in ebook format.
In addition to the various print editions of the hymnal, the Commission on Worship prepared an electronic edition of Lutheran Service Book known as Lutheran Service Builder. This computer program is structured in order to allow churches to easily prepare printed orders of service and electronically presented orders of service, containing readings, hymns, and service music.
