The exhibition, which runs March 31 through May 15, will feature traditional costumes, materials on Scottish language, culture and history and the contributions of such Scottish Americans as John Muir, Andrew Carnegie and Alexander Graham Bell. In particular, the show will focus on Scottish tartans as well as the evolution of the California tartan, which is primarily green and blue with some yellow and red striping.

Library staffer Bruce McDonald, coordinator of the exhibit, said he hopes visitors to the show will get an appreciation for Scottish influences on America.

"Not only did they participate in the founding of the country, but they continue to contribute to its growth and development," he said.

The exhibition is free and open to the public during regular library hours, Monday through Thursday, 8 a.m. to 11 p.m.; Friday, 8 a.m. to 5 p.m.; Saturday, 9 a.m. to 5 p.m., and Sunday, 10 a.m. to 10 p.m. The Oviatt Library is located at the center of the campus at 18111 Nordhoff St. in Northridge.

In honor of the exhibition, the Oviatt Library will celebrate National Tartan Day on Thursday, April 6, at 12:15 p.m. on the lawn in front of the library.

The celebration will feature the "Highlander Band" from Granada Hills Charter High School, the chieftain of the Seaside Highland Games, the chief of Clan California and other special guests.
