In the ACCS, references to Augustine's sermons are to the Benedictine sermon numbering, but Logos links them to the NPNF sermon numbering. Clicking on a ACCS link to an Augustine sermon, when it takes me to NPNF, puts me 50 sermons away from the actual text I want to read.
I reported a "typo" for one instance, but do not think that is best for all the links. Where/how would be best to report this kind of behavior?
