In most cases, the journal's publisher (where applicable) will arrange the application to any indexing service. They also ensure that the correct communications, permissions, and systems are in place in the event of acceptance.
Your Wiley editorial representative will provide feedback on your journal, so you can estimate the likelihood of acceptance.
There are a range of factors used in when deciding whether to index a journal. It is important that these criteria are met before submitting a journal for coverage.
Examples of criteria used by Thomson Reuters
Timeliness of publication: Late or short publication can indicate poor academic reception, and the possibility that the journal will falter in the near future.
Quality of peer review: A journal must have a robust peer review system in order to maintain research quality.
Distinctiveness of subject area: A journal must have a distinctive aims and scope. Companies like Thomson Reuters want to index titles that cause a redundancy or unnecessary addition. You have to show how your title will enrich the database.
Internationality: Unless a journal is regional, you should try to reflect geographical diversity of the subject area in your authors and editorial board.
Number of citations: Journals are often rejected because of low citation levels in their category. This may because a journal is largely uncited, because its main competitors are not indexed and there is no record of articles that cite the journal.
