P. de Corswarem: De liturgische boeken ... O.L.Vr. van Tongeren

P. de Corswarem: De liturgische boeken der kollegiale kerk van O.L.Vr. van Tongeren voor het Concilie van Trente (Gent 1923)

De Corswarem gives an inventory of the liturgical manuscripts of the Onze-Lieve-Vrouwekerk in Tongeren (using old signatures that have changed since), and an analysis of the liturgy of the Mass, the Divine Office, and the liturgical calendar.

Unfortunately some of the manuscripts discussed have disappeared after publication of this book.
