Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
Key features of open video repositories are
outlined, followed by brief description of specific sites relevant to the
social sciences. Although most were created by instructors over the past 10
years to facilitate teaching and learning, significant variation in kind,
quality, and number per discipline were discovered. Economics and Psychology
have the most extensive sets of repositories, while Political Science has the
least development. Among original-content websites, Economics has the strongest
collection in terms of production values, given substantial support from
wealthy donors to advance political and economic agendas. Sociology stands out
in having the most developed website in which found-video is applied to
teaching and learning. Numerous multidisciplinary sites of quality have also
emerged in recent years.
