In doing research about one of my ancestors, I found a record of a hymn that he wrote and received a copyright for, back in 1914. I'm interested in locating a copy of the sheet music, but I have no idea where to start -- this appears to be the only song that he had copyrighted, and Google searches are not providing any useful information.
What I have is an entry in the Catalog of Copyright Entries published by the Library of Congress:
THAT GLAD DAY; hymn, words and music by D. Reid; unacc. 4to. [24032 (C) Nov. 21, 1914; 2 c. Nov 24, 1914; E 349678; David Reid, Boston.
With this information, how would I go about locating the music?
