Great Find! Just briefly looking through the site I found an index of hymnals. One by the School Sisters of Notre Dame was especially interesting as I was taught by this order. The hymnal was from the 1800's and for the stations of the cross in addition to prayers at each station was said the Act of Contrition. We sure have dropped a lot of devotions and methods of praying them.
There is certainly a great deal to learn from having access to books and hymnals from long ago.
