The Dale Warland Singers library includes 270 commissioned works by 116 composers. It is the most important collection of contemporary American choral music in the world, and includes some works that have never been performed and others that are now out of print.

Some highlights: "The Hourglass" by Irving Fine; "Agnus Dei" by Samuel Barber; "The Flower Song" by Vincent Persichetti; "Alleluia" by Randall Thompson; "Every Christmas I Hear Bells" by Dave Brubeck; "Songs of Youth and Pleasure" by Libby Larsen; and "Walden Pond" by Dominick Argento, to a text by Henry David Thoreau.

There are numerous choral arrangements by Robert Shaw and Alice Parker. The Dale Warland Singers commissioned arrangements of traditional folk songs by Stephen Foster, such as "My Old Kentucky Home," and by Hoagie Carmichael, of songs such as "Stardust," "The Nearness of You" and "Georgia on My Mind."

The collection also has music of the standard repertory, such as J.S. Bach's B Minor Mass and Mozart's Mass in C Minor.
