You seem to have indeed but the Greek link seems to point to a moved or removed page SBTS. Is that where it was pointing ?
I reported a correction for it.
This is the excerpt:
1. Sentence Diagram23
A sentence diagram is a visual way of representing the relationship among its words, illustrating relationships by the position of each word and the kind of adjoining line. The method is often called the Reed-Kellogg system, based on an 1877 book that first explained the method.24 Their rules for sentence diagramming are very specific, enabling those familiar with it to see another’s interpretation of a sentence at a glance. The downside is that the rules are too numerous to do more than offer a glimpse of this method here. If you’d like to learn it more thoroughly, consult the source in the footnote for this subsection. Other good sources are available on the internet, for example here: English and Greek.
Footnote 23 though gives reference to another book and the English link in the section is ok
