+In the description of disambiguation methods (1) and (2) above, we assumed that
+each (disambiguated) cite has an unambiguous link to its bibliographic entry. To
+assure that each cite does in fact uniquely identify its entry in the
+bibliography, detail that distinguishes cites (such as names, initials, and full
+given names) must be shown in the corresponding bibliography entries. If this is
+not the case, disambiguation methods (1) and (2) also act on all members of a
+set of ambiguously cited bibliographic entries, until no more entries in the set
+can be unambiguously cited by adding (expanded) names. Each method only takes
+effect on the involved bibliographic entries after it has been used to
