The eighteen volumes of Detailed Reports on the Salzburger Emigrants Who Settled in America (reproduced in sixteen discrete books) contain the diaries and letters of Lutheran pastors who ministered to the Salzburgers, German-speaking Protestant refugees, in Georgia. Samuel Urlsperger collected and edited these writings into the Urlsperger Reports printed at Orphanage Press, Halle, Germany, from 1735 to 1760. The original German publication, Ausführliche Nachricht von den saltzburgischen Emigranten, is available through the Internet Archive, but this English-language translation is not available online.

In the mid-eighteenth century, Samuel Urlsperger of the Lutheran Ministry in Augsburg edited the German edition of the Detailed Reports after having distributed the many reports to the faithful in Germany. He made major deletions for both diplomatic and economic reasons and suppressed proper names. His son, Johann August Urlsperger, succeeded him. He took even greater liberties with the text, deleting large sections and rearranging others. The English version, translated and edited by George Fenwick Jones, a German scholar, restores the deleted sections and the proper names and provides the original sequencing of the material.

The Detailed Reports offer insight into daily life in colonial Georgia and provide precious details and vignettes on subjects that receive less attention in other sources, notably African Americans, women, silk production, and the cost of goods in a frontier colony. The Reports are an underutilized resource for the study of this period and an unparalleled source for the evolution of a rural community during the early years of the colony.
