Jacob Lawrence (1917–2000) examined the African American experience through art. This website was created in 2001 to accompany an exhibition exploring his life and work. The website (with a flash version and an html version) provides a straightforward account of Lawrence's life and work accompanied by images.

The site is presented in three parts, "Beginnings," "The Young Artist," and "Over the Line," each organized as a sequence of pages consisting of short descriptions (50 words) and associated images. There are two short audio clips of Lawrence talking about Harlem and color. The images are relatively small and cannot be enlarged.

This website presents all known correspondence of the wife of James Madison, containing roughly 2,000 letters. Although many letters are thank-you notes or polite responses to social invitations, others offer rich insights into the personality and experiences of the First Lady, especially those exchanged with her sisters. The letters are organized into five periods: birth and youth; the years as wife of the secretary of state; the years as first lady; retirement; and widowhood. Users can search by name, date, topic, or place. A table of contents lists the letters by date, author, and recipient.

Additional features include a biographical sketch; "Crosslinks" listing all names (including nicknames, middle, and maiden) appearing in each letter, in order of appearance; a different color font to highlight unclear or missing characters or words; and a summary of the contents of each letter. Although the site is gated, a free trial option is accessible to all.

This website brings together more than 200 letters, articles, official documents, and illustrations focused on issues of race and reform during and after the Civil War, including unpublished letters written by Northern women who taught freedmen in the South and letters written by their students. Many of the texts are presented in original (handwritten) format and transcription. The website is a combination exhibit, with introductory and explanatory text, and primary source archive.

Materials are available through two paths-through the "Primary Resource Index" or through three topics: "The Freedmen," "Freedmen's Education," and "At War's End" (not yet complete). Within each topic, there are four to seven subtopics, such as "The Emancipation Proclamation" and "Visions of Freedmen in Letters of Freedmen" and at least one subtopic has further subcategories. Each subtopic begins with introductory text, often several paragraphs in length, that provides background information as well as links to relevant documents. The site cautions that "some of the materials on this site are racially offensive." A search is available at the bottom of document pages, but the dedicated search page is not currently working. There are links to more than 100 additional online primary and secondary sources.

In 1851, Massachusetts passed the first law recognizing adoption as a legal and social operation. Since then, adoption has had a rich history in the United States, documented at this website through close to 200 reports, writings, letters, adoption narratives, and other documents. Users unfamiliar with adoption history might begin by exploring the detailed timeline that traces adoption history from 1851 to 2000, when Congress passed the Child Citizenship Act of 2000 eliminating the process of naturalization for international adoptions. Moving on to the Topics in Adoption History section, with in-depth explanations of orphan trains, proxy adoptions, infertility, child welfare, and eugenics, will help build historical context. The Document Archive and Adoption Science sections boast documents from the late 1800s to the present by notables such as Pearl Buck, adoptees searching for information on their biological parents, and court decisions on adoption throughout the 20th century.
