Created by the staff of the Annenberg Rare Book and Manuscript Library at the University of Pennsylvania, this exhibit traces the life and musical career of African American contralto Marian Anderson. Anderson broke the race barrier when she came to prominence in the 1930s and 1940s. The materials are drawn from Anderson's personal papers, which she donated to the University of Pennsylvania in 1993. The exhibit is presented chronologically in 10 sections that explore Anderson's birth in Philadelphia, her education and musical training, and her career and humanitarian efforts toward improving African Americans' opportunities.

The site contains more than 30 audio and six video excerpts from performances and interviews, over 50 images, with approximately 100-word explanatory captions, illustrating Anderson's life and work. This exhibit is ideal for researching African American history and the history of the performing arts in America.

This site offers books and journals related to the science of home economics. Its goal is to document the rise of home economics to a profession, beginning around the middle of the 19th century, and to correct an academic marginalization of the field.

Primarily focused on the years from 1850 through 1925, the site contains digitized texts of 934 books and 218 journal volumes, totaling almost 400,000 pages. Visitors may use the search engine, or look through the Subject index, or browse alphabetically by author, title, or year of publication.

Topics range from Child Care to Housekeeping to Retail. Each entry includes a 500- to 750-word essay, two or three images, a very detailed bibliography (available as a PDF file), and a list of possible subtopics. This is an outstanding site full of primary sources and a great resource for researchers, students, and teachers.

This collection from one of the nation's leading repositories for sources on women's history features photographs, letters, account books, diaries, legal documents, artwork, and memorabilia generated by four prominent northeastern families from the late 18th through the early 20th centuries. The four families—the Bodmans, Dunhams, Garrisons, and Hales—are white, middle-class families, and their experiences represent only a portion of American society in the 19th and early 20th centuries.

This site features 63 documents and images gathered from the families' papers ,and there are two ways to navigate them: by family or by one of four themes (Family Life, Social Awareness and Reform, Arts and Leisure, and Work). Each family or theme has its own page, with short (350–500 word) interpretive text combined with excerpts from the documents. Each excerpt is accompanied by links to the entire document—both a scanned image and a transcription.

The theme "family life" contains documents that reflect courtship patterns over the 19th century, childrearing practices, and 19th-century gender roles. "Social awareness and reform" features items related to the abolition of slavery and changing perceptions of race, and women's suffrage. Some of the materials within "arts and leisure" reflect increased opportunities for professional women artists in the late 19th and early 20th centuries. The "work" theme includes materials that demonstrate the barriers women faced within the workplace. This site, when supplemented with additional resources, can help show students how to use family papers to study U.S. history.
