The present study is not without limitations. By restricting itself to the ProQuest database this
study may not have allowed complete coverage of all empirical articles in the field of
knowledge management in SMEs. Yet, it seems reasonable to assume that the review
process covered a large proportion of the studies available. In addition, reviewing the
literature was sometimes disconcerting, as many papers do not specify whether they are
discussing SMEs or large firms. Finally, this paper proposes some research directions,
which are not exhaustive but represent initial stages.
