“…The hands-on methods represented in this special issue are as diverse as those found in the broader fields that make up infrastructure studies (historical, ethnographic, documentary, and interview-based to name a few), but the methodologies (or theories of inquiry) have coalesced around a handful of approaches that seek to make knowable the complexities of CI. Often conducted by ethnographers that combine participant observation and documentary analysis, these studies can be of the daily meetings of practitioners (as with Monteiro 2010, this issue;de la Flor et al 2010, this issue;and Bietz et al 2010, this issue), interview-based studies (as with Kee and Browning 2010, this issue;Faniel and Jacobsen 2010, this issue;and Bietz et al 2010, this issue) or more virtually by tracking the vast streams of data created in these projects by emails, reports, published papers and online documentation (as with Karasti et al 2010, this issue). These are the moments of 'social shaping of technology' (Pinch and Bijker 1984) that later become black boxed, taken for granted and treated as inevitable.…”
