Presents more than 200 items—including 51 articles, 28 lectures, 84 letters, and 35 photographs—by and about the Nobel-winning geneticist Barbara McClintock (1902–1992). Through experiments with maize in the 1920s and 1930s, McClintock discovered that genetic changes occur when chromosomes break and recombine, a process called "crossing over." In the 1950s, upon finding that genes "jump" around, she investigated the effects of transposable genetic elements.

The site includes an exhibit divided into seven chronological sections with a 4,000-word essay presenting McClintock's career highlights, accompanied by links to relevant documents and visuals. Materials in the collection can be retrieved through searches—basic and also geared to scientists—and in chronological and alphabetical listings. Valuable for serious students of genetics as well as those studying the history of American science and professional women.

Offers approximately 50,000 images of 6,500 items from the papers of 19th-century American scientist and painter Samuel F. B. Morse (1791–1872), inventor of the electromagnetic telegraph. In addition to science and art-related papers, the materials in the collection document Morse's interest in photography and religion, as well as his involvement with the American nativist movement. Includes correspondence, diaries, notebooks, scrapbooks, newspaper clippings, books, pamphlets, broadsides, maps, drawings, and other materials, primarily produced during between 1807 and 1872.

The site provides a timeline supplemented with 15 documents; a family tree; two essays of approximately 1,000 words each (entitled "The Invention of the Telegraph" and "The Lesser-Known Morse: Artist, Politician, Photographer"); a bibliography of 22 titles; and links to 16 additional sites.

Searching capabilities leave much to be desired. Keyword searching applies only to titles assigned to documents by the Library of Congress. Thus even though the finding aid lists "Nativism" as a subject, a keyword search turns up nothing. The site unfortunately is of limited use because of this shortcoming.

This site offers textual and visual historical resources for teaching, learning, and researching the history of women working in the United States. It currently includes almost 3,500 digitized books, 7,500 manuscript pages, and 1,200 photographs. Holdings include letters, diaries, scrapbooks, magazines, catalogs, photographs, books, and pamphlets (both non-fiction and fiction).

Visitors may browse through the "New Additions" area, look through materials by topic (such as home labor, arts, or business), search catalog keywords, or perform a full text search.

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 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 explores the invention and rise of Tupperware products in the 1950s, as well as its impact on women's issues, and its connection to the 20th-century consumer culture revolution. The site focuses on Earl Tupper, the inventor of Tupperware, and Brownie Wise, the woman who created the Tupperware party concept and built a Tupperware empire. Included are short (500-word) biographies of each.

In the Gallery, visitors can see 12 of Tupper's invention notebooks to examine some of his inventions that were not as successful as Tupperware, like his no-drip ice cream cone and his necktie shaper.

The Teacher's Guide offers two learning activities in each of four academic areas: civics, economics, geography, and history. A timeline spans from the 1850s to 2003 and includes events such as the invention of plastic.

Primary Sources includes transcripts of interviews with Tupper and Wise, six video clips from the late 1950s and early 1960s (documenting the annual Tupperware Homecoming Jubilees, which were large gatherings of Tupperware dealers), as well as excerpts from the first Tupperware handbook. Also included are six documents, including a 1960s training manual, How to Sell Tupperware, and a collection of Wise's Aphorisms.

Visitors can share their experiences with Tupperware, either as consumers or as Tupperware dealers, in the Share Your Story section.

Finally, the site features an interview with a noted historian of women's issues who discusses the realities of married women's employment in the 1950s, as well as the impact Tupperware had on women's opportunities.

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 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: .

This curriculum addresses labor politics and economics from the colonial period to the present day. Conceived and written by James D. Brown, Jr, "in cooperation with teachers from the metro Chicago area and local union members," it is divided into 11 chronological sections, each comprised of several elements: a 100–200-word overview; an inventory of major themes, episodes, and concepts; and a feature entitled "Integrating Labor History into Effective Teaching of the Period." This last portion recommends questions and lessons for students, and, for several sections, provides primary source materials. Thus "The Growth of a New Nation" outlines a lesson that asks students to compare Thomas Jefferson's Declaration of Independence with an 1829 essay by George H. Evans—a founder of New York's Working Man's Party—entitled "The Working Men's Declaration of Independence."

The 11 sections emphasize gains achieved by organized labor and invite teachers to "highlight the stark contrast between today's working environment and the relationship between workers and owners of the past." Includes a list of 44 "Significant People in America's Labor History"; a 16-title bibliography; a link to an international news desk providing daily stories dealing with labor groups and issues; and additional material on Illinois labor history.

Some sections of the curriculum are thinner than others. More curiously, the site does not furnish any primary documents from the 20th century, and generally relies more on lists of events and issues than the sort of narrative prose that can enliven the past.

This site was designed to help students research projects about the Vietnam War. It is one of the 20 sections on Spartacus Educational, an encyclopedia of English and U.S. History created by John Simkin, a history teacher. The Vietnam site links to more than 100 sites, including timelines, personal accounts, statistics, visual images, and biographies of figures such as Lyndon B. Johnson and Ho Chi Minh. A smaller, annotated list links to 22 recommended sites.

The site provides students with approximately one hundred 1000 word biographies and email addresses of 11 people willing to be interviewed about their involvement in the war.

The site currently offers two collections of study questions, one produced at the University of California, Berkeley, and one produced by Simkin. Two professional historians host a discussion about the history of the war and help students explore the topic.

The site is slightly difficult to use; however, it is still an excellent resource for understanding the connections between personal experience and public narratives of war.
