Five Acceptable sources for literature review:
Peer-reviewed journal articles:
A peer-reviewed journal article is a paper that is submitted to a scholarly journal, accepted, and published. Peer review is a process where the article is reviewed and verified by a group of scholars before it is published. When authors send their articles to a peer-reviewed journal, the set of experts in the discipline evaluate the paper against all the quality standards and verify it out for publishing. Using peer-reviewed journal articles is an acceptable source for literature because the expert checks the article to see if the sources are reliable and the information it provides is useful and meaningful.
A journal article is a set of multiple articles published on a regular basis. They are shorter than books and are written on a very specific theme. The journal articles are written by experts, so they are reliable sources of data for writing literature reviews. You find them in the form of print, digital, or both. But it is advised to use the journal articles cautiously and sparingly because trade journals are not usually peer-reviewed. It means that they may have flaws in terms of the sources and information presented in the article. However, you can easily find out if they are peer-reviewed articles or not by reading about the journal or simply filtering your research for peer-reviewed ones.
Edited academic Books:
