This site features an online selection of Spalding's Official Base Ball Guide (1889–1939) and the Official Indoor Base Ball Guide (1903–1926). The collection reproduces 35 of the guides, which were published by the Spalding Athletic Company in the late 19th and early 20th centuries. The guides featured statistics, photographs, editorials from baseball writers on the state of the game, and analysis of the previous season for all the Major League teams and for many of the so-called minor leagues across the nation.

Highlights include a host of World Series statistics. For example, the 1939 World Series saw attendance of 200,833 in four games. Total receipts totaled $851,168, and each member of the winning New York team received $5,782.76, while members of the runner-up Chicago team received $4,674.86.

Visitors can access the full text of each edition. The collection is searchable by keyword and browsable by title. Of interest to sports historians or historians of leisure or American culture.

Designed to provide support for elementary, middle, and high school history teachers, this site makes the entire American Memory collection at the Library of Congress available for classroom learning. Using the more than 7 million digital sources available through American Memory's 100 collections, the creators have written and collected 140 lesson plans for teaching American history. Organized chronologically and thematically, the lesson plans are detailed suggestions for classroom activities. Each has a recommended age group and uses primary sources collected by students or teachers from American Memory.

Especially useful are the included guides on using primary sources, using American Memory resources, and using digital or Internet sources in the classroom. A "Professional Development" section offers online workshops and tutorials to improve teachers' digital literacy. An excellent resource for the classroom, this site would be useful to both student and teacher.

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 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.

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 uses about 45 sources to document the planning and construction of the New Jersey Turnpike, opened after two years of construction in 1952.

Building It contains a 1,000-word history of the turnpike's construction, as well as eight primary documents from the planning stages of the highway, including an early map of the proposed route. A dozen promotional documents (pamphlets, public announcements, bond solicitations) and newspaper coverage are also available as is a narrative account of tensions in Elizabeth, NJ, where more than 200 citizens were displaced to build the highway.

Driving It includes 10 accounts from many of the first to drive along the turnpike, advertisements from Howard Johnson's and other turnpike concessionaires, and an excerpt from a 1950s film on highway safety.

Telling It features 16 primary sources, 10 driver stories, and accounts from toll collectors, as well as the story of the first highway worker to lose his life on duty in 1967.

Three Detour sections allow visitors a little diversion with short activities: visitors can match up song lyrics that mention the turnpike with the artists who wrote them (Bruce Springsteen and Simon and Garfunkel are included).

For teachers, the site includes an annotated bibliography of works for various age groups.

This site includes digitized versions of 28 Utah newspapers as part of the Utah Digital Newspapers project. Currently, the site contains more than 600,000 pages. Researchers using this digital archive may browse each individual newspaper by issue, or elect to search by keyword, article title, weddings, deaths, and births.

The site also features a map that users can scroll over to determine which counties in Utah had newspapers that are currently archived in this database, and the dates covered.

The collections begin in 1879, and feature PDF versions of the newspapers.

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.
