Style manuals are important guidelines for formatting of the research produced by researchers. Each journal demands specific formatting of the contents prior to acceptance of research based contents. Therefore, links to some of the important style manuals are given below for the convenience of the researchers, students and faculty.
Journal Impact Factor
The impact factor is an indicator of journal quality. A measure of the frequency with which the "average article" in a journal has been cited in a particular year, the impactor factor is calculated by dividing the number of current citations to articles published in the two previous years by the total number of articles published in the two previous years. Ultimately, the impact factor will help you evaluate a journal's relative importance, especially when you compare it to others in the same field.

The number of libraries owning a journal is an indication of the impact and importance of the journal. Go to 'advanced search' and search by title or ISSN. Look at the 'libraries worldwide' link.
Citation Analysis or citation tracking is a way to see the impact of an article in its field. Also, it's a great way to use a "landmark" or influential article to find more recent, related articles that cite the landmark article.
Go to "advanced search" and use the "references" field.
