Also, just a reminder that a key centre for expertise in systematic review (particularly social sciences, but also healthcare etc.) is the EPPI Centre, based at the UK's Institute of Education (University College London) and funded by a range of public-sector and professional organisations. It has tools and advice for carrying out systematic reviews, as well as examples, and also an ongoing blog https://eppi.ioe.ac.uk/cms/Default.aspx?tabid=53
