The authors define the "Monday crust" and reiterate its familiarity to analysts. They cite various references in the literature, but stress the fact that the particular aspects of "Monday crust" as seen in disorders of the self have not been considered. From the vignettes of two patients who suffered after weekend absences, the authors show how the understanding of the disorders of the self helped elucidate many of these patients' difficulties. Thus they interpret the patients' material in terms of Kohut's ideas of early deficit. They illustrate how the restoration of the "self-object transference" that occurs on Monday repairs the damage; i.e., fragmentation that resulted from the weekend loss of the self-object. The readers will have to judge for themselves whether the patients' pathology is explained on that basis.
