Editorial services play an important role in lives of most of the researchers, as they want their manuscripts to be of superior quality, as the work will be demonstrated before the community of researchers across the world. For that purpose, the researchers want their manuscripts to be free from all kinds of errors regarding subject matter, theoretical foundation, language, grammar, and formatting. Now, if the editorial houses across the world are being looked at, then it can be largely seen that the services being offered by the service providers are majorly confined into three different areas, namely proofreading, copyediting, and substantive editing. If being watched loosely, then it can be misunderstood that these services are focused at perking up the quality of language and grammatical approach of the manuscripts, whereas in actuality, there are more to it. For example, if any editorial house receives a highly technical research based manuscript for substantive editing purpose, then devoid of having a good grasp over the subject it can never be possible on the part of that editorial house to carry out substantive editing on that very document. Therefore, an editor, who is in charge of carrying out a substantive editing of the research based manuscripts, he / she must have a good grasp over the subject. Driven by this logic, in almost all editorial service providers across the world, there are teams of subject experts, who are from a diverse range of academic domains. This is done intentionally, as whenever any requirement comes from any domain of academics; the editors will be able to handle those requirements in the most effective manner. Therefore, it is imperative for an editorial house to employ subject experts as editors, as they will be able to provide the organization with superior competitive advantage over others.
