The Lotta Van Buren Collection came to Brigham Young University in two segments; one in 1955 consisting of a wardrobe of authentic Elizabethan costumes, a collection of old musical instruments, sheet music and a library of books about the instruments; and another in 1960, consisting of the personal papers of Miss Van Buren and her husband Henry Bizallion. The valuable instrument collection is composed of seventeen instruments, including an authentic chest of viols, all in playing condition. The two treble viols, the alto, the tenor, and the bass viols were built between 1660 and 1773. One of the bass viols was owned by George Frederic Handel. the keyboard instruments include two clavichords, a virginal, a spinet, and a two-manual harpsichord. A lute, a cittern, a vielle, (or Hurdy-Gurdy), an alto recorder, a Biblical psaltery, and a Pythagorean monochord are the other instruments. The collection has become an integral part of musicological study at Brigham Young University, enabling students to learn old music first hand by preparing and participation in programs utilizing the instruments.

The personal papers consist of recital programs, photos, research notes, lectures, sheet music, news clippings of her concerts, mementoes, and letters written both by Miss Van Buren and Mr. Bizallion. Nearly all of the letters were generated as part of the process of donating the collection to Brigham Young University.

Sheet music, newspaper clippings, research notes, recital programs, lectures, and correspondence. The items largely relate to her activities in restoring old musical instruments and in teaching about music history and theory.
