Designed to explore the historical similarities and contrasts, ethnic diversity, and interactions between Brazil and the United States, this site contains almost 1,000 images from the rare book, manuscript, map, print, and photographic collections of the Library of Congress and the National Library of Brazil.

The site includes letters (including letters from Thomas Jefferson concerning the independence of Brazil), illustrations, 18th-century maps, and other textual items, including poetry.

The sources are available in five categories: "Historical Foundations," "Ethnic Diversity," "Culture and Literature," "Mutual Impressions," and "Biodiversity" (right now, only the Historical Foundations section is completed). The site is viewable in both English and Portuguese, and is appropriate for high school and college students, as well as teachers and researchers.

This site presents nearly 1 million pages of Vietnam War-related research materials. It includes the full text of more than 80,000 documents, 60,000 photos and slides, hundreds of interviews with veterans and other participants, streaming audio and video recordings, and much more. The more than 685,000 pages of documents include official government and military records, unit and operation action reports, unit rosters, staff journals and morning reports, personal letters, and diaries. The collection grows by some 20,000 pages of new material each month.

Visitors may find useful the Acronym Database (to help with those mysterious and persistent military acronyms). The search engine has been recently updated, and no longer supports simple searches; all searches are advanced. The archive limits the number of users at any one time, due to licensing issues, so the site may be unavailable during times of heavy use.

Convenient, powerful, and massive, this site is invaluable for research into Vietnam units, individuals, and operations.

This site introduces Emma Goldman—an immigrant, an advocate of free love, a promoter of birth control, and an anarchist. The designers have done a splendid job in tying the many facets of Goldman's public life together into one set of interrelated narratives. An "Introduction" is divided into 13 thematically coherent sections, such as Early Years, Anarchism, Use of Violence, and Deportation. Each runs approximately 500 words. A Timeline is useful for placing Goldman into historical and cultural context.

There are several dozen artifacts, including the full text of two books, six cartoons, four historical documents, an analytical essay, two personal letters, 12 news clippings, and 16 photographs. The information is well documented, and includes a detailed bibliography.

The care that the producers took in explaining potentially confusing or problematic terms (like feminism and suffrage) makes the site particularly appropriate for high school and undergraduate students. Although not a comprehensive archive, this site nonetheless provides an informative introduction to Goldman and her role in American history.

This site contains 6,834 digital images related to Japanese American internment during World War II. The War Relocation Authority exhibited these photographs to present the camps in a positive light.

Users can view the site three ways: "Standard" provides a collection summary; "Entire Finding Aid" lists the series descriptions in more detail; "Online Items" lists all 6,834 images complete with a thumbnail and brief description for each image.

Visitors can also search by keyword, though the search works differently depending on which view is being used. The easiest way to use the search is to choose the "Online Items" view, in which a search for "school" will list images with "school" in the description.

Images in the collection come from a number of relocation centers throughout the country, including ones in Colorado, Arizona, Wyoming, and Arkansas.

"Scope and Content" is a 250-word explanation of the site's contents with a brief paragraph about the historical significance of the photographs.

Designed to commemorate the 400th anniversary of the French landing in North America, this site is a collection of primary sources related to the French presence in what would later become Canada, the Great Lakes region, and Louisiana. Exhibition features 350 primary sources, including engravings, portraits, other artwork, as well as documents. They are organized by theme and are easy to find and view.

Database includes a database of more than 6,500 documents, including correspondence, reports, and maps. A special viewer allows visitors to zoom in and out of documents, making close viewing possible.

The collection is searchable by date, author, subject, or keyword. Visitors should keep in mind that although the site is written in English and French, the documents are written exclusively in French. The wealth of primary sources makes this a valuable resource for researchers, but language may prove a barrier for students and teachers.

This site offers 10 unpublished plays (four sketches or skits and six full-length plays) written by American folklorist Zora Neale Hurston. Although the plays were written and submitted to the Copyright Office between 1925 and 1944, they remained unknown until 1997. The plays reflect Hurston's life experiences.

As an anthropologist and folklorist, Hurston traveled the American South, collecting and recording the sounds and songs of African Americans. Her research in Haiti is reflected in the voodoo scenes and beliefs woven into several of the plays.

The collection holds approximately 700 digitized pages. These are scanned as she wrote them and have not been transcribed. This site would be useful for research in early-20th-century southern or cultural history.

This site captures the recollections of 23 former slaves, born between 1823 and the early 1860s. Several of the people interviewed were more than 100 years old. In the recordings, subjects discuss their entire lives, not just their lives as slaves, but they provide an important glimpse of what life was like for slaves and freedmen. They discuss how they felt about slavery, slaveholders, how slaves were coerced, their families, and, of course, freedom.

Each of the 23 subjects' testimony is presented in four formats: Real Audio sound, MP3, Windows WAV, and transcription. Many of the subjects sang as part of their testimony; those songs are collected here, as well.

Visitors should not miss the Faces and Voices from the Presentation section, where photographs and short biographies are posted for seven of the subjects. The father and grandfather of one of the subjects, George Johnson, were owned by Confederate president Jefferson Davis. Johnson shares his recollections of Davis.

This site contains extraordinary primary sources, and is a tremendous resource for research into slavery and Reconstruction.

This site introduces users to the life of George Washington. Reflecting current scholarship, the site contains an Introduction, which is essentially a 4,000 word summary of Washington's life and career. The Timeline is a chronology of the milestones in his life, with a few references to national events. The Multimedia Room includes 11 audio clips of scholars discussing Washington's importance in the second half of the 18th century. Also included are four sound files of Pat Sajak reading memorial letters written by Thomas Jefferson and Winston Churchill, among others, and five video clips of Charlton Heston reading some of Washington's more famous letters and speeches (his Farewell Speech, for example).

The site contains a modest collection of 150 Washington letters, and a transcription of Washington's Book of Etiquette, which Washington himself transcribed when he was 16 years old. The letters are divided into pre-revolutionary, revolutionary, pre-presidential, presidential, and post-presidential collections; and include personal letters from and to Washington and his wife, as well as documents like presidential pardons, indenture documents, and land surveys. Teachers will find useful the 10 Lesson Plans (for grades 9-12), which are very detailed and include bibliographies. Listen to the audio review: .
