The Elizabeth Wright collection predominantly contains materials relating to Richard Wagner and family members. The materials cover a wide range, including memorabilia, such as a Wagner-themed card game and a ceramic plaque of Richard Wagner, an original note by Siegfried Wagner and facsimiles of letters by Wagner, original photographs of Wagner family members as well as facsimiles and prints of Richard Wagner and others, original advertisements and programs of Wagner's operas, a radio transcript and a typescript about Wagner's composition and staging, and a series of prints depicting scenes from Wagner's operas.

There are also several items not related to Wagner. These are a letter from W. Somerset Maugham, an autographed print of mezzo-soprano Mariana Paunova, and prints of other composers such as Beethoven, Mozart, Liszt, and Richter.
