Most people think of the Amon Carter Museum in Forth Worth as a trove of Wild West paintings and sculptures by Frederick Remington and Charles Russell.

Those works did serve as the nucleus of the collection when the museum opened in 1961, but anyone who visits the Amon Carter in its recently expanded home — featuring an addition of 20,000 square feet, comprising new gallery space plus a library and high-tech storage rooms — will walk away with a far different impression. Turns out that extra space was sorely needed: The museum’s holdings now number 250,000 paintings, sculptures and photographs from the 19th and 20th centuries, including prints by Elliot Porter, a pioneer of color landscape photography, as well as Dorothea Lange, Ansel Adams, Laura Gilpin, Berenice Abbott and Edward S. Curtis. The museum also owns all of the final black-and-white prints from Richard Avedon’s famous series, “In the American West,” a portrayal of the American working class that was sponsored by the museum in 1981.

The Carter also built a cozy new home for its library, one of the top two research libraries for American art in the country, according to museum director Rick Stewart. Located in the basement, the library is finished in warm Burmese teak veneer, and its thousands of books and documents about American art are all are accessible to the public, by appointment. 3501 Camp Bowie Boulevard, (817) 738-1933.
