ICTD benefits from being a broad multidisciplinary field that unites researchers from a wide range of domains attempting to understand the role of ICTs in the context of social, economic and political development. As a new field of study, however, ICTD continuously grapples with epistemological differences and varying (and often evolving) notions of what counts as development, and there still exists a significant gap in outlining where the current boundaries of this field lie. In this paper we present "Missing Pieces," an ongoing research project with the primary aim of uncovering the constitution, development, growth and impact of ICTD. Through in-depth quantitative and qualitative analyses of the distribution of participation in and impact of ICTD research across places, people, institutions, organizations and funding agencies, this project will look beyond just trends, and instead focus on finding the missing pieces, i.e. what, or rather who is being left out.
