Students at the Corcoran School of Art may someday be sculpting and painting in a location some blocks away from the Corcoran Gallery, with which the school is affiliated. The only fully accredited independent art school in the city is considering moving to a new location, said William Barrett, its dean, Friday.

Barrett said the Corcoran School had commissioned a space study about a year ago from architect Paul Spreiregen. The recently completed study says the school needs "considerable space" just to engage in "the usual activities" that lead to a bachelor of fine arts degree. But with printing presses, kilns, easels and the like jammed in a small area behind the Corcoran Gallery, it has become crowded.

The school has always been located within one or two blocks of the Corcoran. Though it was founded in 1890, it didn't have its own quarters until 1897, when it began holding classes in a small annex behind the Renwick Gallery. By the time that building was torn down to make way for the New Executive Office Building, the school had moved to its present site.

The next move, though, may not be to a building that looks very much like a conventional school or museum. Barrett said school officials have agreed that they do not want to locate the school outside the city. But, he said, "we don't need a K Street level of finish." The school needs "good, open space, and a lot of light," said Barrett, who mentions loft buildings, warehouses and old department stores now vacant as possible sites. "You can go into those spaces, throw up a few partitions and you're on the way."

Corcoran School officials hope a larger facility will allow for more students and an expansion to include a master's degree program. Reviving a Baseball Bard

Baseball is poetry to many. And so the Library of Congress is releasing Aug. 1, in record and pamphlet form, the poem that was made famous by an ex-husband of the late Hollywood columnist Hedda Hopper.

He was actor DeWolf Hopper, who made Ernest L. Thayer's poem, "Casey at the Bat," an American classic in the late 19th and early 20th centuries, reciting it some 10,000 times beginning in 1888, says American history specialist James Gilreath.

When the library's publications department requested a project, Gilreath gave it some thought. "I started thinking about baseball," he says. "Earl Weaver was back in, and the Red Sox were in first place."

Researching "Casey," Gilreath listened to Hopper's rather histrionic recordings, one made in 1909 and one in 1927, and says he found them hilarious.

"When you listen to him do it, you can't ever read 'Casey' in the same way," he promises. And it doesn't take long to listen: The recording is 5 minutes, 40 seconds long. "He prided himself on that because he had done it so often," says Gilreath. Odds and Ends

Among the works at the Source Theatre's sixth annual Washington Theatre Festival is a lone film called "Persistence of Vision," a modern retelling of the Orphean myth, directed by Andy Zmidzinski and starring Kathryn Kelley and local actor Steve Dawn. It screens Fridays and Saturdays at midnight through Aug. 16 . . . The National Museum of Women in the Arts has released the title of its inaugural exhibit: a not unexpected "American Women Artists, 1830-1930." It features works by Mary Cassatt and Cecilia Beaux. The inaugural poster features Lila Cabot Perry's "Lady With a Bowl of Violets" . . . The D.C. Youth Orchestra kicked off its brief summer season with a concert Friday afternoon in Western Plaza. The orchestra leaves Aug. 19 for a tour of China. Museum's Cornell Collages

The National Museum of American Art announced last week that it had been given 119 collages and box constructions of the late sculptor and assemblagist Joseph Cornell by the Joseph and Robert Cornell Memorial Foundation. Nine of the pieces will go on view in August. Save That Architecture

Keeping the Smithsonian Castle looking like a castle will be one of the tasks of the Smithsonian's new Office of Architectural History and Historic Preservation, which will be responsible for preserving and enhancing the institution's architectural heritage. The office will also assist staff, scholars and the public in finding architectural information pertaining to institution's buildings, which run the gamut from Romanesque to contemporary.
