The Marian Osgood Hooker Collection consists of two albums dating from 1894 to 1896, which document Marian's growing interest in photography while a student at the Marlborough School for Girls. Both albums include images of Marian's classmates, friends, and family.

The first album, titled "Marlborough Maidens," is a photographically illustrated manuscript which contains posed photographs that complement two original publications with rhymed prose, "Sub Rosa" and "Symposium." The models and authors of these productions were probably several of Marian's classmates from the Marlborough School for Girls, including Henrietta Visscher, Alice Gertrude Paul, and Mary Cutler. In "Sub Rosa," the girls are posed as Greek goddesses, with accompanying poetic text that makes reference to Marian acting as the "photographic maid" who "tempted maidens three from school, to shoot them with her deadly tool." "Symposium" consists of a series of vignettes, such as "The Marlboro Sirens," "A Carnival in Madrid," and "A Rhymed Tragedy." These vignettes are also composed of original rhymed text and posed photographs of the girls dressed in several costumes, including a Japanese orchestra, a Fiji chief, a nun, and several other characters which serve to illustrate the text. This album also includes hand-drawn decorations around the margins and on the cover.

The second album includes candid photographs of Marian's classmates and faculty at the Marlborough School, scenes of home life at the Hooker residence, Marian and her friends play acting, outdoor scenes, and several photographs of Italy, probably from Marian's 1896 trip to Europe with her mother. There are no captions. The majority of photographs in this album are circular snapshots, suggesting that Marian had used a KODAK camera (revolutionary at the time) to take the photographs. Other photographs appear to be formal studio portraits. Some pages in this scrapbook have light foxing. The album dates from around 1894 to 1896.
