examine how emerging organizations acquire shape by drawing on multiple organizational forms, a process we call
organizational bricolage. Studying Indymedia London, a grassroots media collective, we propose a grounded theory of
organizational bricolage that identifies how various types of organizational forms are selected and how they are instantiated
into the organization. Whereas extant research has emphasized imprinting as a primary mechanism shaping newly founded
organizations, we point to the additional role of organizational values. Emerging organizations augment their imprinted forms
by using ancillary forms aligned with their organizational values and reinforce their core features by differentiating themselves
from antagonistic forms that conflict with their values. We contribute to the literature on organizational formation by
developing a process model that details how imprinted forms are subsequently modified. Moreover, we extend theories of
bricolage by specifying the limits to the relative arbitrariness of bricolage as an activity, and we contribute to the study of
organizational values by suggesting that they act as a focusing device shaping organizational structure.
