Overview of Journal Indexes and Aggregators
From MPublishing
Once your journal launches, you will want to do everything you can to establish its reputation and raise its profile. One way to do both of these things is to get the journal listed in relevant indexes, aggregators, and databases. Which ones matter most will vary depending on your discipline. This page provides an overview of some of the most important resources, with some basic information about each, including links to review their selection criteria and submit your title for consideration.
Thomson Reuters Web of Science/Web of Knowledge
The Thomson Reuters Web of Knowledge/Web of Science is (self) described as "the world's largest collection of research data, publications, and patents." This database is used to determine the Journal Impact Factor (JIF), a proprietary number assigned to each journal based on how frequently articles from the last two years are cited in newly published scholarship. JIFs, along with other information, are published each year in Journal Citation Reports. Web of Knowledge covers scholarship in all disciplines, though JIF tends to be more important in the sciences (and especially health sciences) than in other fields. Thomson also has domain-specific sub-databases (such as BIOSIS) that draw from the Web of Knowledge. A journal must first be in the Web of Knowledge in order to be represented into one of the sub-databases.
Special notes: Timeliness of publication is essential. Journals under consideration must submit three consecutive new issues to Web of Knowledge as they are published, to demonstrate that they stick to their schedule. (Journals that publish articles one at a time must submit all new content to Web of Knowledge as it is published, over a 9 month period. Journals that do not meet the basic timeliness criteria will not be evaluated further at all for inclusion.
Scopus
Scopus is owned by Elsevier. It calls itself "the largest abstract and citation database of peer-reviewed literature."
Scopus includes scholarship from across all disciplines and offers journal analytics using several different parameters.
