I have a need to use hereinafter cited as in order to define much-shortened forms of certain source references. Most of the examples I have seen have been for the citation of legal cases, where the legal mode of reference is quite different from our genealogical style. However, in my case, it's to shorten the overall volume of citations, which is already overbearing. An elided form of the wording, as is normal for short-form citations, wouldn't reduce the volume to the level that I want.
My question concerns the punctuation for the inclusion of this phrase. The examples I have seen put it in a separate citation layer, but what if the first layer of the citation ends with something like "..., p.10;" or "..., entry for ...;"? Is there a potential ambiguity as to whether the new reference is to the containing source or the specific part therein?
