If you are one of the sixty million Americans who trace their heritage to German-speaking lands, you are probably already familiar with Don Heinrich Tolzmann's prolific dissemination of books on German-American history and genealogy. In this two-for-one reprint, Dr. Tolzmann has combined related books originally published by the Department of Historical Research of the Carnegie Institution of Washington. The original works are Marion Dexter Learned's Guide to the Manuscript Materials Relating to American History in the German State Archives (1912) and Albert B. Faust's Guide to the Materials for American History in Swiss and Austrian Archives (1916). According to Dr. Tolzmann's introduction, these octogenarian books are still of value because of their specific focus on the German-Americana materials within the archives. Genealogists may discover many new avenues of research through the cited sources that deal with emigration from the German-speaking lands to settlements in the U.S. This publication also stands out among guides to German archives for covering Austria and Switzerland as well as Germany. The extensive name and subject indices from each of the original books are included in this reprint. These indices will guide the researcher through the plethora of mostly 18th and 19th century citations of political papers, passenger lists, personal diaries, diplomatic letters and other materials. These materials are arranged in descending order from cantonal to municipal institutions, so items may also be looked up by region using the table of contents.
