As research datasets and analyses grow in complexity, data that could be valuable to other researchers and to support the integrity of published work remain uncurated across disciplines. These data are especially concentrated in the “Long Tail” of funded research (Heidorn, 2008; Ferguson, et al., 2014; Borgman, et al., 2016) where curation resources and related expertise are often inaccessible. In the domain of astronomy - which relies heavily on sophisticated instrumentation - it is undisputed that “dark” uncurated data exist, along with data at risk of becoming dark in the future (Cragin, et al., 2010; Borgman, 2015; Darch & Sands, 2015). However, the scope of the problem remains uncertain. My dissertation project implements a mixed-methods research approach to characterize the Long Tail in astronomy as well as the properties of uncurated and at-risk astronomical data, and to develop methods for locating potentially-useful data to be targeted for curation through indicators in the scholarly literature.
