In the field of geographical limology, the new science of international borders, it is possible to distinguish several consecutive theoretical approaches that can be seen as either traditional or postmodern. At each consecutive stage new approaches have been applied together with, not in place of, the traditional, in order to continue to perfect the discipline (see, for instance, Minghi, 1963; Rumley and Minghi, 1991). Traditional approaches, such as historical mapping, the typological, the functional and the political, have been described in previous theoretical works (e.g. Kolossov and O'Loughlin, 1998; Kolossov and Turovsky, 1998; Kolossov and Mironenko, 2001). Here we are concerned with the postmodern approaches, which have been emerging mostly during the 1990s and the present decade.
