This book would be great to have on Logos/Verbum. This book is great for preserving the chant of the church for those who can't chant very well. In addition, this book has the offertory antiphons absent in the current versions of the Roman Missal. I would love to be able to highlight and annotate, in addition to translate this through logos/verbum. It's available for free on the internet so it might not be hard to add to verbum.
