This site highlights Orville and Wilbur Wright's pioneering aviation work that led to the world's first powered, controlled, and sustained flight. The collection contains approximately 49,000 digital items, including correspondence, diaries and notebooks, scrapbooks, drawings, printed matter, and 300 glass-plate photographic negatives. The papers cover the years 1881-1952, although the years 1900-1940 are especially well represented. The diaries offer detailed records of the brothers' ideas, as well as their successes and failures; and photographs include the first flight, taken at Kitty Hawk in December 1903. The materials are particularly valuable because the brothers so carefully documented their work and ideas, and because they corresponded so often with members of their family.

The site includes a Wright Brothers timeline and a Wright family tree. This site would be of particular use to anyone interested in the Wright Brothers or the history of flight, but is also useful in examining the role of photography in history and invention.

This website contains articles and extracts about early radio and related technologies in the United States from 1897-1927. It is organized chronologically and divided into 24 sections. Each section is a long-form essay, containing numerous hyperlinks to reproductions or transcriptions of original primary documents, including documents relating to the efforts to provide entertainment and news over the telephone in the first decades of the 20th century. Essays vary in length, most 1,000 - 2,000 words, and many are original essays by the site's creator. The first section offers an overview of the individuals, activities, and technical advances that characterize the early 20th century.

Designed to document American scientist Linus Pauling's role in the early 1950s race to discover the structure of DNA, this site contains more than 800 primary sources. Some 650 documents and photographs provide an unusually frank glimpse into Pauling's life; much of the correspondence in the collection is between Pauling and other front runners in the race (Watson and Crick, for example, and Rosalind Franklin). In addition to the documents and photographs, the site includes 16 of Pauling's published papers, 15 unpublished manuscripts and notebooks, and 22 audio and video clips of Pauling. There is a thorough chronology, which details the personal and professional dimensions of Pauling's life, including his troubles with the State Department and their refusal to issue him a passport on the basis of national security. Professional rivalries and personal jealousies, as well as victories and triumphs, are all documented in correspondence and in video interviews.

Although Pauling lost the DNA race, he was eventually awarded two Nobel Prizes. In addition to a typical search feature, Linus Pauling Day-By-Day allows viewers to learn about events and to examine selected correspondence relevant to any given day, from January 1952 through December 1953.

An exhibition of 18 works by one of America's great artists, Thomas Eakins (1844-1916), with annotations of 100-300 words on each image. Eakins, known for applying Paris-learned Beaux-Arts techniques to realistic depictions of his own Philadelphia milieu, often painted persons engrossed in everyday actions: sailboats racing and oarsmen rowing on the Schuykill River; surgeons overseeing students operating on patients; a concert singer performing; a baby playing; and coach horses trotting through Fairmont Park. Although most of the images —which date from 1871-1902—are reproductions of paintings, the exhibit also includes a preparatory drawing, a photograph of the artist's anatomical casts, and two photographic studies, one influenced by the pioneer motion studies of Eadweard Muybridge. As the exhibition text notes, scholars have recently discovered that Eakins used projected photographs to create his works.

Also included are expressive portraits of Eakins' friends and contemporaries, including poet Walt Whitman, who wrote that Eakins was "not a painter, but a force"; controversial anthropologist Frank Hamilton Cushing; and sculptor William Rush engaged in transforming a nude model into a mythic image. Valuable for students of the history of art and for those interested in realistic depictions of late 19th-century life and culture in Philadelphia.
