Established in 1980, the National Association for Olmsted Parks (NAOP) is a coalition of various design and preservation professionals concerned with the legacy of landscape work left by noted landscape designer Frederick Law Olmsted Sr. and his colleagues. On their website, visitors can learn about Olmsted's primary works via a master list of design projects by his firm and some profiles of some of his most prominent work, including Central Park and the landscape at the Biltmore Estate. Scholars will want to look through the "Research" area for resources that include a set of suggested links and an extensive bibliography. Visitors will also want to look at the "News and Publications" area for more details about the NAOP's work and their newsletter.
