One to two pages is normal; but, I have submitted a few three-to-four-page evaluations when I believed an article was already fairly outstanding but might be improved. I try to be careful not to leave out important details that later readers might find interesting.
Generally speaking, the longer the better. The more you write about the subject and the more you convince your readers of how great this article is, then others will want to read what you have to say. However, longer reviews may deter some readers who only have time for short comments or submissions. So, go ahead and write about whatever it is that has you excited, but keep in mind those wanting more detail may not have time for a full-blown evaluation.
The best reviews include the facts about the article and its author as well as their own personal opinion of the piece. They can be funny or serious but must be unbiased and objective. Positive reviews help other people find useful information while negative reviews discourage them from purchasing similar products in the future. For example: "I liked how the author pointed out why hydrogen fuel cells are better than lithium ion batteries," or "I thought the article lacked clarity in some parts but overall it was helpful."
Short reviews (one to two paragraphs) are perfect if you are commenting on a podcast, video, or forum post.
In the absence of particular directions, a common rule of thumb is that the length of your literature review should be commensurate to the length of your overall report. If your work is 15 pages lengthy, 2-3 pages for the literature review may adequate. However, if you have 20 pages to speak, then 5 pages could be allotted to the review.
The purpose of the literature review is not only to describe previous research on a topic but also to determine what new evidence has emerged since the original studies were conducted. As such, it is important that you review all relevant publications, including older studies if they offer additional insights into the topic. You should also consider publishing articles or presenting papers at conferences that address related topics or findings from earlier studies on your subject. This will help ensure that you have covered everything relevant to your topic and will give you more opportunities to build upon existing work.
In conclusion, a good literature review should cover both recent and old studies on a topic while providing sufficient detail about each study cited. It is helpful if you can start with a general question in mind and search for answers by reading the titles and abstracts of various studies. This will help limit the number of articles you read in full and save you time.
A excellent review knows no bounds. It can be between 70 and 2000 words long. The more words, the better.
The goal of your review should be clear from the title. It should give an idea of what will follow and not include any major spoilers. A good review also includes some summary at the end, but that's optional.
There are two types of reviews: critical and non-critical.
Critical reviews are written by people who have seen or read the book being reviewed. They usually take the form of essays - longer articles that discuss different aspects of the book. These reviews are most useful for readers looking for extended discussions about the book's themes or significance.
Non-critical reviews are simply written reports of what was done and what happened. They can be between 100 and 1000 words long. These reviews are useful if you want to share your views on the book with others, for example using blog reviews.
Long reviews are valuable contributions to the literature and can help authors when they decide which books to write about next. However they do require time and effort, so please only write them if you have the necessary resources.
