I am finding that liturgical books, especially those I am unfamiliar with, are more difficult to use in Logos/Verbum than in dead tree format. This is essentially because of the lack of the ubiquitous ribbons. For example, our morning and evening prayer begin with instructions as to where to put your ribbons. In some traditions those "ribbons" go to other books.
I do not expect Logos to tag the resources in this manner. However, it would be VERY helpful if Labels allowed us to enter a URL that was easily clickable. For example, in this resource:
Alford, Henry. The Year of Prayer: Being Family Prayers for the Christian Year Suited to the Services and Commemorations of the Church. London; New York: Alexander Strahan, 1866.
to be able to create a link to "special Prayer for Christmas" would be highly desirable. A simple electronic replacement for the ribbon.

Being able to share these would mean only one (knowledgeable) person would have to mark up a book.
