Since 1989 the student organists at DMLC/MLC have used the Hymn Prelude Index to find a organ prelude, or postlude to an assigned hymn. Today more and more churches are using piano and other instruments in their worship services. This index has been expanded to include instrumental music for hymn preludes.

This collection is an index to the organ and instrumental music holdings of the MLC Library. Users can search by hymn tune, composer, or Christian Worship or Christian Worship Supplement hymn number. We continue to include new hymn tunes and titles as they are added to the MLC Library music collection.
