As with the articles in this issue, this introduction reflects the views of the authors and does not necessarily reflect the views of the U.S. Department of Housing and Urban Development.

When discussing the themes emerging from this series of articles, we are struck by the diversity in both the content and methods covered in these contributions. We also commend the authors’ desire to grapple with complex questions surrounding homelessness and service provision. We can readily identify evidence gaps that this program of research helps to fill, but if we take a more global perspective it seems that considerable value could be added to this science by engaging with the existing international literature and situating these findings in that broader context.
