On-campus resources can be found in Preus Library, an outstanding facility for a college the size of Luther with seating for more than 1,000 students and a collection of more than 340,000 volumes, subscriptions to more than 1,000 periodicals and newspapers, and a 400-volume rare book room. There are three especially impressive historical collections at Preus Library: one of Norwegian-American history; another concerning the Lutheran Reformation and the college's namesake, Martin Luther; and the Luther College Archives, which houses the official records of the college dating from 1861 as well as unofficial papers of faculty and student organizations.
Extensive off-campus historical resources can be found at Vesterheim Norwegian-American Museum, located in Decorah's business district. The museum houses one of the largest and finest ethnic-heritage collections in the United States. Originally part of the college, the museum is open to Luther students at no charge.
