The Systematic Reviews of the Cochran Bias Methods Group has an extensive bibliography, which is not reproduced in the reading folders. "This group strives to raise awareness of the problem of bias and is exploring important questions with respect to the epidemiology of research results and outcomes. The Cochrane BMG is also investigating a range of different forms of bias, such as ‘publication bias’, language bias’, and ‘outcome reporting bias’."
