Choosing the right journal to publish your research

To ensure the results of your research gets published, reaches the right audience and delivers maximum impact, it is important that you choose the right journal to publish your manuscript. It should satisfy certain criteria to maximise chance of getting your article published. For a start, you can ask senior colleagues in the field with experiences in publishing research for a list of reputed journals you can submit your article to. Alongside that, you can search reputed catalogues of international journals for a list of indexed journals that are likely to accept submission of articles from your area of research. Online tools are available to help you choose the right journal for your publication. Check out the following:

Elsevier Journal Finder Search for an Elsevier journal by name or use the Elsevier Journal Finder by entering your abstract to find journals best suited for your research.

Springer Nature Journal Suggester   Enter your abstract or article description to find Springer journals best suited for your research.

Journal/Author Name Estimator (JANE) JANE matches your title, abstract, or keywords to millions of documents in MEDLINE to help determine the best journals for your research.

The U.S. National Library of Medicine (NLM) Catalog. You can search for journals referenced in the NCBI Databases.

Be aware of increasing numbers of predatory journals that promise quick publication of your research. Think. Check. Submit is an international cross-industry initiative aiming to “educate researchers, promote integrity, and build trust in credible research and publications”.

Consider the recommended checklist at the official website.

The video here shows you how to identify the right journal and avoid predatory journals in 3 simple steps — think, check and submit.

Measuring Research Impact

Research metrics are indices used to measure research performance, both at journal- and author-level. There are several metrics that measure journal or article impact factor. To-date, the Journal Citation Reports (JCR) from Web of Science remains the most popular resource for journal impact data. The well-known JCR metric, the journal impact factor (JIF), measures the frequency with which the average article in a journal has been cited in a particular year or period. JIF measures the impact of a journal, not that of individual articles.

The JIF of a journal is usually provided on the journal’s website. If you wish to know the ranking of journals in your field, you must access the source data, for which you may need a subscription. More about citation analysis here.

Several other metrics have emerged and are gaining recognition as well. Amongst them are:

Tracking Your Own Publication Metrics

Sign up for an ORCID iD to link together all of your works and make them discoverable by others. Your iD is a unique identifier. It makes it easy for others to find your research output.

If you have a Google account, Google Scholar Citations can help you keep track of citations to your published articles. You can check who is citing your publications, visualize citations over time, and compute citation metrics.

Set up your personal Google scholarly profile in few simple steps. Get started by logging in using your Gmail (Google) account. If you do not have an account, create one here.

You can also find your (author) h-index at:

Web of Science  and  Scopus

The SCImago Journal Rank (SJR) is another free journal ranking resource for authors. SJR is derived using an algorithm like the Google PageRank system. It uses journal information contained in the SCOPUS® database.

SJR indicates the average number of weighted citations received in a selected year by the documents published in the journal during the three preceding years.

Publish or Perish is a Hartzing’s software program that uses Google Scholar and Microsoft Academic Search to retrieve and analyze academic citations to obtain statistics on journal and author citation metrics.

SNIP (source normalized impact per paper) by Leiden University’s Centre for Science and Technology Studies measures the average citation impact of the publications of a journal. It is based on the Scopus biblio-graphic database produced by Elsevier, which includes about 20,000 journals.

Unlike Web of Science’s JIF, SNIP only includes citations from selected sources and selected document types, but SNIP is corrected for field differences. Access to SNIP is free.

Google Scholar provides a free journal ranking resource for researchers. Google Scholar Metrics uses the h-index to quantify an individual’s scientific research output. Google Scholar enables authors to track citations to their own articles. It also computes the impact of journals which are ranked by their h5-index and h5-median. Metrics are derived from the last 5 calendar years of a publication's output.

Altmetrics is an alternative measure of the impact of a scholarly work in that it takes into account both the quality and quantity of attention it is receiving through social media, citations, and article downloads.
