The genealogical listings included with this collection were created by staff at the Nebraska State Historical Society using Family Tree Maker 7.0, a software application for building and maintaining genealogical databases. This particular form of output is a "register report." It presents the basic details recorded in registers of births, marriages, and deaths.
Staff at the Library of Congress took the output in a word-processor format (RTF) and converted it to HTML for presentation on the World Wide Web. Modifications including adding internal links to descend the family tree, simplifying the use of different font sizes, and ensuring that the tagging of tables followed guidelines from the Library of Congress and the World Wide Web Consortium.
