Question: how do you track down the references to check on patristic citations cited in NA27?
My Answer: good question, I'm not familiar with any easy way to do this (and it is even worse in UBS4 which has expanded patristic support, but no indications of source material). [I have expanded my actual historical ipsissima verba answer with some things I have thought of in writing]
- Basically if the passage is in the Catholic Epistles then the ECM gives references and supporting evidence.
- If it is in Luke then the IGNTP gives references and page numbers in editions.
- If it is in Matthew or Mark then Legg gives selections of texts with some reference (although it doesn't always seem complete).
- Otherwise check Tischendorf 1869 (but you have to figure out his referencing system and then you may have to check an old edition of the cited work; and remember that not all patristic works have standard referencing conventions).
- Also try Tregelles 1857-1879 (Tregelles aimed to collect all the patristic evidence of the first three centuries, the 'early Citations' 'with full references to the passages in the works themselves').
- If none of these help (or are available) then start at the other end with the Biblia Patristica which indexes scripture citations in church fathers.
- If it is a controversial passage references (and discussion) can often be found in the secondary literature (detailed commentaries of the type that discuss the text and/or journal articles etc.).
- Remember that TLG is fairly well stocked with Greek patristic literature which can be searched for specific word combinations.

UPDATE 2013 (TW):
Here are two additional resources for patristic citations:
1. International Greek New Testament Project: Bibliography on work on the NT text of Greek authors
Recently, IGNTP committee members Rod Mullen and Mike Holmes, both involved in the SBL series The New Testament in the Greek Fathers, took the initiative to compile a bibliography of work on the New Testament text of Greek authors.
The list "keeps track of recent work on establishing the biblical text in patristic writers. It includes the volumes published in the SBL New Testament in the Greek Fathers series, as well as a list of work in progress."
The Biblindex = Index of Biblical Quotations and Allusions in Early Christian Literature is maintained by Laurence Mellerin et al. of the Institut des Sources Chrétiennes. It includes all the 270.000 references in the published Biblia Patristica volumes, and an additional ca. 130.000 references on Athanasius of Alexandria, John Chrysostom, Theodoret of Cyrus, Procopius of Gaza, Jerome and more. Access to data is free, after registration. This is a real treasure trove.
