Archives and Museum Collections

The Olmsted Archives is one of the most widely researched museum collections in the National Park System, containing over 1,000,000 historic documents.

Park and city planners from across the United States use these records each year to rehabilitate and rebuild many of the nation's most significant and beloved landscapes to the lasting benefit of millions of people. Historians, students, and preservation planners use the collection to document historic areas and to produce exhibits, films and scholarly publications.

The National Park Service has cataloged and conserved the collections which contain landscape photographs, initial surveys, field sketches, general plans, planting lists, presentation drawings, business records and scale models.

Researchers have the opportunity to survey and study historic records related to parks, gardens, communities, estates, and campuses designed by Frederick Law Olmsted and the Olmsted firm, including:

Acadia National Park, Maine
Atlanta Parks, Georgia
Baltimore Park System, Maryland
Boston Park System, Massachusetts

Olmsted Research Guide Online (ORGO)

With the Olmsted Research Guide Online (ORGO), it is possible to search a single database for records held at the Olmsted National Historic Site and the Olmsted collections at the Library of Congress: plans and drawings, photographs, lithographs, planting lists and correspondence.

ORGO features a "Master List" search that allows researchers to search for Olmsted projects through a variety of access points: client name, historic job number, project type, city and state. In addition, ORGO includes a database with basic document information such as date and author/draftsman responsibility, as well as information on specific microfilm locations to simplify interlibrary loan requests from the Library of Congress. The database can be accessed at www.rediscov.com/olmsted.


Archival Collections at Olmsted NHS

The surviving records of the Olmsted firm are held primarily at the Frederick Law Olmsted National Historic Site and at the Library of Congress in Washington D.C. Originally together in Brookline, these collections complement each other and are often best studied in tandem.

The archival collections held at the Olmsted National Historic Site date from 1839 to 1980. The collections include an estimated 139,000 landscape architectural plans and drawings, 70,000 sheets of planting lists, 60,000 photographic prints, 30,000 photographic negatives, 12,000 lithographs, financial records, job correspondence, records and reports, and models relating to over 5,000 design projects. The Archives also contain study and reference collections on urban design, landscape architecture, and the fine arts in general.

Archival Collections Elsewhere

The bulk of the firm's earlier correspondence (ca. 1885-1950) is located in the Frederick Law Olmsted Papers and Olmsted Associates Records held by the Manuscript Division of the Library of Congress in Washington, D.C. A guide to the Olmsted materials at the Library of Congress gives an overview of both collections.

The Papers of John Charles Olmsted (1852-1920) are held by the Frances Loeb Library, Harvard Design School.

Often, materials from other repositories will prove useful to a researcher's work. The Smithsonian Institution holds the Archives of American Gardens. The Catalog of Landscape Records in the United States, formerly at Wave Hill and now located at the New York Botanical Garden, lists landscape records generally including plans, drawings and photographs that are contained in other repositories across the country.
