Permit me to offer a few words of advice before taking on a review. The narrative review that is part of a term paper, thesis or dissertation is a time-honored review method. Bench scientists, clinicians and graduate researchers venturing out into the world of evidence-based reviews or systematic reviews need to be aware of the tremendous amount of time and effort that is required to properly perform one of these reviews.
In particular, the research question MUST be strictly defined and clearly stated. Otherwise, the review is doomed to fail. I cannot over emphasize this aspect of the research process. A vague or multifaceted research question will cause the research process to grind to a halt at the research synthesis phase and you will then have to revisit the project from the beginning.
Also, if a poorly performed review is submitted to a journal for publication, the editor will summarily reject it.
While some editors are very polite in their rejection letters, others are not and will question your scholarly and scholarship credentials. All this is presented so that you understand what is required. If you are willing to take on this task, the best of luck and the Reference Librarians stand ready to guide and assist you.
