This is a Mennonite book.

This site is a little confusing. Follow the link near the bottom to The Harmonia Sacra Handbook. That's where index to authors, composers, first lines, etc. is. Get your page number an go to the Typeset music for the words & music in pdf files of 10 pages each. The first type page links to 7 shape settings; which is how the book was published. There's a link on the 7 shape page to 4 shape settings because a lot of us Sacred Harp singers can't handle 7 but want to sing the music.
