A collection of more than 1,100 topographical maps created by the United States Geological Survey from the 1890s to the 1950s covering all of New England—Maine, New Hampshire, Vermont, Rhode Island, Massachusetts, and Connecticut—and selected areas of New York. The maps—which reveal roads, buildings, rail lines, bodies of water, and elevations—occur in 15-minute and 7.5-minute quadrangle series (a minute is one-sixtieth of a degree of latitude or longitude). In addition, the collection includes six maps with 30-minute quadrangles.

For states other than New York, users can view a state image map and select a point within a grid marked off in 15-minute increments to find listings for available images accompanied by dates the maps were surveyed, created, and revised. Towns within each quadrangle are also listed along with names of adjacent areas. Users also may search an alphabetical list of towns within each state. For New York, only an index of quadrangles names is available. Maps are presented in JPEG format. According to the site, "Each image is typically 2 megabytes, so download times are likely to be slow." A useful site for those studying changes in the New England landscape during the first half of the 20th century.

This private collection presents more than 15,800 rare historical maps with a focus on North and South America. The collection is accessible via several formats. A standard browser (the "directory") is designed for use by the general public. In addition to two browsers and a "collections ticker" requiring Insight software (available for free download), a GIS browser shows detailed overlays of maps and geospatial data for the more serious researcher.

Many of the U.S. maps are from the late 19th and early 20th centuries and are often notable for their craftsmanship.

Most of the maps are excerpted from 20th-century historical atlases. The site will be particularly useful for research in military history and early 20th-century urban history.

Due to copyright restrictions, only a small portion of the more than 25,000 digitized items from the Hannah Arendt papers can be viewed outside of three locations. Visitors who are not at the Library of Congress, New School University in New York City, or Carl von Ossietzky University in Oldenburg, Germany, may, however, view almost all of the collection's documents relating to the Adolph Eichmann trial and Arendt's book, Eichmann in Jerusalem. Material in this collection includes correspondence with holocaust survivors, minutes of the trial, Arendt's notes, and positive and negative reviews of the book. About one quarter of Arendt's general correspondence from 1938 to 1975, arranged alphabetically by correspondent, is available. Visitors may access eight folders of notes, lectures, fiction, and poetry from the 1920s and 1940s and all of Arendt's appointment books from 1972 to 1975. All material is in facsimile, much of it in German. Most of a collection of lecture notes, correspondence with students, and royalty statements for Arendt's books from 1949 to 1975 is available offline. Nearly half of a collection of drafts of Arendt's books, On Revolution and Between Past and Future may also be accessed from any location. Although limited, the site will be interesting for research on Arendt, modern Europe, and philosophy.

An exhibition on Jewish life in America emphasizing the themes of accommodation, assertion, adaptation, and acculturation. The website features more than 200 illustrations, portraits, and images of books and documents from Library of Congress collections. The website offers an explanatory overview of the exhibition and four brief electronic exhibits focused that help to tell a part of the Jewish story in America from 1654 to the present. Some of the items highlighted by the exhibition include the first book printed in the English settlements of America, The Bay Psalm Book printed in 1640, the first published American Jewish sermon, and a hand-drawn plaque from c. 1942 with dual Hebrew prayers for Winston Churchill and Franklin Roosevelt. A small bibliography lists 10 books plus six books for children. The site provides an introduction to the Library of Congress collections and is useful for teaching about the history of Jewish life in America.
