Indexing of Journals and Indices of Publications.

Journal indexes are indicators toward the quality of a journal. Authors, researchers, and the audience need some criteria to judge which literature they need to read or which journal they need to send their article to. Journal indexes help the respective groups to make this decision. From Index Medicus to Web of Science, journal indexes use different criteria to judge the quality of a journal or an article. Figures like impact factor and CiteScore also rank journals and articles based on various criteria so that the audience and authors can make their pick. Author indices like h-index and ResearchGate score aid in comparing scientific work done by authors and researchers. Indexes of journals, publications, and authors therefore offer a classification of medical literature from which the best can be chosen depending on the requirements in their respective fields.
