Stephen D. Chakwin's article in the March/April 1987 issue of the American Record Guide, pages 8-10, was the source of quotes included in reviews of Symphonies No. 1 & 7, and 6 & 9, as well as of the "They reveal him to be an interpreter greatly concerned with conveying the music's drama. . . ." quote in the second paragraph of the introductory remarks.

Michael Mark's article in the March/April 1986 issue of American Record Guide, p. 5, was the source of quotes included in the reviews of Symphonies 2 & 5, and of Symphony No. 6 "The Pastoral." Also reviewed in that article are the overtures to Egmont and Consecration of the House.

The booklet Age of Revolution, by Frederic V. Grunfeld and the editors of Time-Life Records (New York: Time Incorporated, 1966), was the major source of the photographs included, in cropped and otherwise altered form, in the Beethoven montage. Pierre Boulat provided the Vienna Woods photograph; Charles Phillips provided the photo of the W.J. Mähler portrait of Beethoven; Claude Michaelides provided the photograph of Baron Lejeune's "Battle of Marengo" from which the detail of Napoleon was derived. Erich Lessing's photograph of the painting of the city of Vienna (School of Martin van Meytens' "Entry of Isabella of Parma into Vienna") is reproduced in Henry Anatole Grunwald's booklet Age of Elegance. Both booklets were part of the 1966 Time-Life series The Story of Great Music, which presented representative works of major composers conducted by such leading conductors as Klemperer and Beecham for the Angel Records label.

The cropped and retouched detail of Dr. Klemperer conducting the November 12, 1957 performance of Beethoven's Ninth Symphony in the Festival Hall, London, is from a photograph by Brian Seed reproduced in the booklet accompanying the two-record set of that performance: Beethoven Symphony No. 9 "Choral," Incidental Music to Goethe's "Egmont," Angel 35662/35663.

The photograph by the Austrian Information Service of Beethoven Walk in the Vienna Woods was originally reproduced in Virtuoso: The Magazine of the Virtuoso Society, The Klemperer Issue, 1965. The version used to illustrate the Pastoral Symphony review was computer-colorized exclusively for this Web site.
