A database of citations to over 13,000 liturgical titles printed in Europe between 1450 and 1600, with listings of holding libraries in the U.S. and Europe. It is designed for musicologists studying organ and choral music, art historians searching for named engravers and artists, general historians studying aristocratic patronage, scholars of poetry, and specialists in church history and early printed books. The records were created by the School of Music and are copyrighted by the University of Michigan Regents. The National Endowment for the Humanities supported this project. The RELICS database information is based upon personal inspections of books in most of the major research libraries of the U.S. and also libraries in a few selected European cities, bibliographies, and library catalogs.
