Citations support the communication of specialist knowledge by allowing authors and readers to make specific selections in several
contexts at the same time. In the interactions between the social network of (first-order) authors and the network of their
reflexive (that is, second-order) communications, a sub-textual code of communication with a distributed character has emerged.
The recursive operation of this dual-layered network induces the perception of a cognitive dimension in scientific communication.Citation analysis reflects on citation practices. Reference lists are aggregated in scientometric analysis using one (or sometimes two) of
the available contexts to reduce the complexity: geometrical representations (‘mappings’) of dynamic operations are reflected
in corresponding theories of citation. For example, a sociological interpretation of citations can be distinguished from an
information-theoretical one. The specific contexts represented in the modern citation can be deconstructed from the perspective
of the cultural evolution of scientific communication.
