Founded in 1976 by members of the Ohio's museum community, the Ohio Museums Association (OMA) works with a variety of museums, museum professionals and providers of museum services to strengthen the state's museum, foster excellence in the field and support the museum community. The Ohio Museums Association serves the diverse Ohio museum community by providing a forum for support and communication to enhance the ability of institutions to serve the public interest. OMA serves Ohio arboretums, aquariums, anthropology museums, art museums, art center and galleries, botanical gardens, ethnic museums, general museums, heritage centers, history museums, historic houses, historic parks and sites, historical societies, natural history museums, nature centers, planetariums, science and technology centers, youth and children's museums and zoos.

The Ohio Museums Association has partnered with the State Library of Ohio, the Ohio Historical Society, LYRASIS, the Intermuseum Conservation Association and the Ohio Local History Alliance to create an invaluable advocacy resource for Ohio's museum community: The Ohio Connecting to Collections Brochure!
