American Memory:  Technical summary

Pioneering the Upper Midwest: Books from Michigan, Minnesota, Wisconsin, ca. 1820-1920

Future American Memory Collection

Collection Overview

This collection of books from Michigan, Minnesota, and Wisconsin, ca. 1820-1910 is comprised of first-person accounts and other primary documents of social and political history that illuminate the development of the states of Michigan, Minnesota and Wisconsin from the early nineteenth to the early twentieth century. The land and its resources; the conflicts between settlers and Native peoples; the experience of pioneers and missionaries, soldiers and political reformers, European immigrants and former slaves; early leadership in business, medicine, and education: all this and more comes to life in these works, which map the distinctive character of a heartland region.

Technical features
Searchable text for book-length documents (average about 170 pages) written by different authors in different periods, diverse vocabulary offers challenges in pinpointing paragraphs on same (detailed) topic. In addition to page-images, separate images for illustrations and tables are available in two formats, for display and for printing. This collection was scanned in two batches. Halftone illustrations in the second batch were captured using a new approach to avoiding the moiré patterns associated with scanning halftones.
