"High-impact journals" - those considered to be highly influential in their fields. A journal's impact factor is a measure of the frequency with which an average article in a journal has been cited in a particular year.
Tier 1. High category (3.5-4) Peer-reviewed publications in one of the following: • Journal with Impact factor that falls in the top 25 percentile ranking based on the impact. factor within the subject, discipline, or sub-disciplinary category (refer to APPENDIX.
Scientific Reports publishes the most articles of any journal in the world and it has the quality you'd expect. Its impact factor is higher than that of PLOS One because of a handful of physics articles that get published there each year that rack up a ton of citations.
Academic rigourOne among many, Scopus is an “abstract and citation indexing database of peer-reviewed literature: scientific journals, books and conference proceedings” owned by the Elsevier publishing firm (Elsevier, scopus).
The higher the impact factor, the more highly ranked the journal. It is one tool you can use to compare journals in a subject category. The top 5% of journals have impact factors approximately equal to or greater than 6 (610 journals or 4.9% of the journals tracked by JCR).
Overview: Published for over 200 years, The New England Journal of Medicine aims to bring the best research to clinicians and health educators. It has the highest impact factor of any general medical journal in the world.

You can search for an individual journal to find out its impact factor or search within a subject category to find out which are the highest impact journals in that field. To use Journal Citation Reports, go to the Library Databases page and search for InCites JCR.

The annual JCR impact factor is a ratio between citations and recent citable items published. Thus, the impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years (see Figure 1).

Some examples of credible, peer-reviewed journals are JAMA, the Journal of the National Cancer Institute, the New England Journal of Medicine, and Science. If you have any questions about whether a journal is peer-reviewed, ask a librarian or your health care provider.
The impact factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. It is used to measure the importance or rank of a journal by calculating the times it's articles are cited.
The h index is a metric for evaluating the cumulative impact of an author's scholarly output and performance; measures quantity with quality by comparing publications to citations. The h index corrects for the disproportionate weight of highly cited publications or publications that have not yet been cited.
Hirsch reckons that after 20 years of research, an h index of 20 is good, 40 is outstanding, and 60 is truly exceptional. The advantage of the h-index is that it combines productivity (i.e., number of papers produced) and impact (number of citations) in a single number.
Check to see whether the journal is still in publication and/or whether the title has it ceased publication. If it is the latter, consider whether the subject/expertise is no longer 'in vogue' or current and/or whether the field has been superseded by something that is more current.
Use the Journal Citation Reports (JCR) available through the Web of Knowledge service. To check the impact factor of a specific journal you can search by title. Otherwise, you can browse by subject (subject categories are brought together in the Science and Social Science strands).
The ISI 5-Year Impact Factor is the average number of times articles from the journal published in the past five years have been cited in the given Journal Citation Report (JCR) year.
It was calculated as the sum of the impact factors of all the publications an academic had. For example, if an author had been an author on four papers with impact factors 0, 2, 4, and 3. They would have 0 + 2 + 4 + 3 = 9 impact points.
Impact factor is commonly used to evaluate the relative importance of a journal within its field and to measure the frequency with which the “average article” in a journal has been cited in a particular time period. Journals with higher IFs believed to be more important than those with lower ones.
