The aim of this survey was to describe academic librarian roles in systematic reviews (SR) in any discipline, as a follow-up to a previous survey of Canadian academic health sciences librarians. A convenience sample of librarians at Canadian universities who support SRs were invited to complete a survey. Respondents were asked about their roles, training, knowledge, and barriers to providing SR services. Ninety-four librarians responded to the survey. The most common roles were in the literature search; time and training were the most frequently reported barriers. Librarians are supporting reviews in multiple, diverse disciplines, primarily as expert searchers.
