One factor to consider when selecting journals for publication is the scholarly merit of the publication. Journal Impact is a good starting point to help you determine the best journals in your field.
The Impact factor of a journal is often considered highly relevant when determining a suitable vehicle in which to publish your research. The impact factor is a number derived by dividing the number of citations to articles published over a two year period in a particular journal, by the number of articles published in the same journal over the same two year period. The impact factor denotes the anticipated average number of times an article in a journal will be cited over a two year period. So theoretically, the higher the impact factor, the more prestigious the journal.
An impact factor as a simple number is relatively meaningless. It is often more useful to note that the journal you are interested in ranks 6th out of 106 journals in the field.Journals rankings are indicated in Journal Citation Reports:
