Does the Cover Letter Really Matter?

Many journals require a covering letter alongside the submission process. Some of them, particularly elitist journals, pay a particular attention to the cover letter to such extent an editor may decide not to send a paper out for external peer-review because of a 'bad' or absence of a covering letter. As stated in the instructions of many journals, the goal of the covering letter is to emphasize the novelty and to communicate the potential implications of the reported findings. Authors are also invited to tell the handling editor how the topic is related to the journal's scope and to demonstrate how the results fit in broader context of the literature. Here, I briefly discuss if the cover letter is really necessary.
