"[This book] concentrates upon a strongly bonded family during a period of separation that is necessarily preserved in much greater detail than their happier moments spent in one another's company. Being based to a large extent on letters that surely were never intended for the eyes of anyone outside the family and an intimate circle of friends, it also gives a more spontaneous view than most journals offer. These letters, preserved for more than eleven decades, are the record of years during which the Ernst Coreth family began really to enter into the affairs of its new homeland. No wish to magnify the importance of these people, no intent to dramatize their fate motivated the accompanying study, for much of what the Coreths experienced other immigrants experienced also"--Preface.

This "work is organized by subject. Materials are grouped under twelve main sections in the body of the work, with appropriate subdivisions and subtopics within each main subject. Each section is assigned a two-letter designation, and entries are numbered consecutively within each section. This subject code system was designed to facilitate referals from the Index to the main body of the text, and to allow for cross-referencing between sections."--Introduction.
