Dear Dr. Hisham,

Literature review is an overview of the literature in the scientific/ research field— covering findings of the previous researchers, analysis/ comparison of findings of different researchers, current status of research and future directions of work in such a field. Some reviews may cite as many as a thousand references of published research papers. On the other hand, literature survey may be a summarized version of the comprehensive review of the literature. It is generally much shorter in length, and will not cite exhaustive list of references of published research papers in the field. Literature review is much more extensive than a literature survey.
