“…In the same study, the authors noted that literature searches performed by information professionals tended to be carried out using more resources than those without. More recently, it was suggested that the involvement of a librarian not only helps with selection of databases and other sources, but also with the development of a search strategy to retrieve eligible studies [34]. In a recent article, Rethlefsen et al showed that librarian participation was significantly associated with search reproducibility and better reporting in general internal medicine systematic reviews [35].…”

Objective: A critical element in conducting a systematic review is the identification of studies. To date, very little empirical evidence has been reported on whether the presence of a librarian or information professional can contribute to the quality of the final product. The goal of this study was to compare the reporting rigor of the literature searching component of systematic reviews with and without the help of a librarian.Method: Systematic reviews published from 2002 to 2011 in the twenty highest impact factor pediatrics journals were collected from MEDLINE. Corresponding authors were contacted via an email survey to determine if a librarian was involved, the role that the librarian played, and functions that the librarian performed. The reviews were scored independently by two reviewers using a fifteen-item checklist.Results: There were 186 reviews that met the inclusion criteria, and 44% of the authors indicated the involvement of a librarian in conducting the systematic review. With the presence of a librarian as coauthor or team member, the mean checklist score was 8.40, compared to 6.61 (p,0.001) for reviews without a librarian.Conclusions: Findings indicate that having a librarian as a coauthor or team member correlates with a higher score in the literature searching component of systematic reviews.Keywords: Systematic Review, Librarian, Critical Appraisal, Literature Search, Reporting There is ample literature assessing the quality of systematic reviews across many disciplines [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], and a common theme that has emerged from a number of these studies has been the need for improving the conduct and reporting of systematic reviews. Many studies have advocated for and described various roles that librarians and information professionals could play on a review team [17][18][19][20][21][22][23][24][25][26]. Several standards and organizations also suggest that a librarian or information professional be involved in the review process [27][28][29][30]. Documents produced by the Campbell Collaboration and a recent Canadian Institute of Health Research (CIHR) Knowledge Synthesis grant competition strongly recommend that an information professional or librarian be included among the members of a review team [31,32].However, to date, there has been very little empirical evidence on whether the presence of a librarian or information professional on a systematic review team contributes to the quality of a systematic review. Golder et al. found that only a very small percentage of reviews reported their search strategy with enough detail to be reproducible, and of those with reproducible searches, nearly half employed an information professional [33]. In the same study, the authors noted that literature searches performed by information professionals tended to be carried out

“…Expert searching has long been acknowledged as a core function of health sciences librarians [1,2], and the perceived value of librarian-conducted expert search activities has been documented [1,3], Librar ian involvement in complex searches, including systematic reviews and meta-analyses, is a natural extension of experience with mediated expert search es. In addition to designing and constructing thor ough and replicable searches, librarians can add value to systematic review teams by forming an swerable research questions, identifying information resources, collecting and managing search results, and writing descriptive methodologies [4].…”
