Hi. Unfortunately, many review writing services provide poor quality services. The length of a standard literature review may vary depending on the aims and objectives of the writing. Generally speaking, for academic purposes the volume can be between 1000 to 5000 words and for journal publications between 500 to 1500 words. However, it is important to remember that the quality of a review is not determined by its length, but depends on how fully and accurately the author has described the main ideas and arguments of the work, as well as how competently and logically the structure of the review has been organised. Therefore, it is important to pay attention not only to the length, but also to the quality of the writing of the literature review. If you decide to buy a literature review paper, choose good services.
