I Need a Hymn for a Funeral

A patron called to ask, if we have the sheet music to Swing Low, Sweet Chariot.  He was wanting me to find the sheet music, copy it, and email it to him.  We don't have that song in our collection, so I went to Google first.  My initial search was:

"sheet music:  swing low sweet chariot"

The first items were images of the sheet music.  I knew the hymn, itself, was in the public domain, but I didn't know about the various arrangements.  The fifth image was from the Duke University Library.  This link led me to the book:  Negro Spirituals arranged for solo voice by H.T. Burleigh.  I sent them a link to the book https://library.duke.edu/digitalcollections/hasm_n0697/ so he could make a copy if he need to do so.
