Theses and dissertations
Theses and dissertations can be difficult to find. They are not published and are not indexed in a consistent method.
Theses often contain unpublished primary research, statistics and findings. This can be particularly relevant if the findings contradict those in published forms, and are therefore highly important in helping to minimise publication bias.
