Alternatively, you can seek help from your librarian to find out which databases, journals, authors, and articles would be the most relevant to you. Once all the relevant literature has been gathered, it should be organized as follows:. Answered by Editage Insights on 08 Aug, It is alright for authors to ask the reviewers for clarifications regarding their comments.

In such a situation, authors may require more clarification to be able to make the required revisions. Generally, peer review is single-blind or double-blind. In any case, authors do not have direct contact with the reviewers and their only point of contact is the journal editor. Therefore, in such instances, the editor should make sure messages are being communicated effectively in both directions. It is the duty of the editor to convey all the reviewers' comments to the author.

Answered by Editage Insights on 13 Aug, This content belongs to the Conducting Research Stage. This is where the thesaurus helps. The records might even contain links to full-text copies of the works themselves. If not, and you want a copy of the work, you will have to find out if your library carries the journal or has the book and the hard copy on the library shelves.

Be sure to ask a librarian if you need help. In addition to entering search terms into PsycINFO and other databases, there are several other techniques you can use to search the research literature. First, if you have one good article or book chapter on your topic—a recent review article is best—you can look through the reference list of that article for other relevant articles, books, and book chapters.

In fact, you should do this with any relevant article or book chapter you find. This works because other researchers working on your topic are likely to be aware of the classic article and cite it in their own work. You can also do a general Internet search using search terms related to your topic or the name of a researcher who conducts research on your topic.

This might lead you directly to works that are part of the research literature e. The search engine Google Scholar is especially useful for this purpose. A general Internet search might also lead you to websites that are not part of the research literature but might provide references to works that are. Finally, you can talk to people e. When you do a literature review, you need to be selective. Not every article, book chapter, and book that relates to your research idea or question will be worth obtaining, reading, and integrating into your review.

Instead, you want to focus on sources that help you do four basic things: a refine your research question, b identify appropriate research methods, c place your research in the context of previous research, and d write an effective research report. Several basic principles can help you find the most useful sources.

First, it is best to focus on recent research, keeping in mind that what counts as recent depends on the topic. You will get a feel for what counts as recent for your topic when you start your literature search. A good general rule, however, is to start with sources published in the past five years. The main exception to this rule would be classic articles that turn up in the reference list of nearly every other source. If other researchers think that this work is important, even though it is old, then by all means you should include it in your review.

Second, you should look for review articles on your topic because they will provide a useful overview of it—often discussing important definitions, results, theories, trends, and controversies—giving you a good sense of where your own research fits into the literature.

You should also look for empirical research reports addressing your question or similar questions, which can give you ideas about how to operationally define your variables and collect your data. As a general rule, it is good to use methods that others have already used successfully unless you have good reasons not to. Finally, you should look for sources that provide information that can help you argue for the interestingness of your research question.

For a study on the effects of cell phone use on driving ability, for example, you might look for information about how widespread cell phone use is, how frequent and costly motor vehicle crashes are, and so on. How many sources are enough for your literature review? This is a difficult question because it depends on how extensively your topic has been studied and also on your own goals. This gives a rough idea of what professional researchers consider to be adequate. As a student, you might be assigned a much lower minimum number of references to use, but the principles for selecting the most useful ones remain the same.
