Orthodox Church Fathers
Apparently some of the footnote references are off by a couple in some
of the volumes. That is, the actual footnote is a couple of
references above the one linked. Reader beware.
The particular case that was brought to my attention is in
NPNF1-10/npnf1-10-91.htm. Footnote  is extraneous.
I'll try to fix this in the next edition.
