Where to Publish: choosing a journal: Journal impact

Tools to measure researcher impact

Scopus Journal Impact
If you haven't already run your Scopus search click on the Find journals by subject tab here and then select Scopus.


Scopus has three metrics to compare journals. When you click on Compare sources and view CitScore, SJR and SNIP data
the CiteScore data appear first.


CiteScore measures the citation impact of journals. "It is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published [in that journal] in those same three years."

The higher the score of a journal, the greater the impact as measured by citations.


To view a list of journals ranked by CiteScore click here.
You can look at ranked lists by subject areas or look at individual journal titles.


SJR is the Scimago Journal Rank measure. It’s a prestige metric based on the number of citations received by a journal in a particular year and the prestige of the journals that make those citations.
You can use SJR as a part quantitative and part qualitative measure of journals.


SNIP  (Source Normalized Impact per Paper) is a normalised metric to take account of the subject area. This allows some comparison of journals in highly cited subject areas with journals in disciplines where there are fewer citations. You can find a list of publications ranked by SNIP here. You can search by main subject area and subareas and limit to journals, books, conference proceedings and more.

Contact your Research Librarian if you need more help with journal ranking.

Incites Journal Citation Reports produces journal impact factors for many individual journals and also compares journals in broad subject groups.

Today we'll search for the impact factor and rank of the journal
developmental medicine and child neurology

Most of the journals covered are in STEM (Science, Technology, Engineering and Medicine) or social sciences. More than 11,000 "scholarly and technical journals" are included.

You can look for past dates but most people want the latest impact factor.
Incites Journal Citation Reports covers two broad ranges of journals:-

The Science Edition (SCIE) and the Social Sciences Edition (SSCI)

SCIE = Science Citation Index Expanded
SSCI = Social Sciences Citation Index

Notice you can limit to Open Access only.

Click on the Rank button to see where this journal ranks in the list of all journals within the Subject Categories assigned to the journal.



Journal Relationships

You may find it useful to look at Journal Relationships . These are journals that are likely to cover topics that are similar to those covered in the journal under examination, but this is less accurate than using Scopus or EBSCO Research Databases.


Top Ranked Journals in a Category

It's often useful to find the top ranking journals in a particular field.

Scroll to the top of the screen and on the right hand side click on a category of interest.


The ranked list by journal impact factor for the category is displayed.

Google Scholar Metrics

This resource ranks journals by h5-index.

The h5-index is the h-index for articles published in the last 5 complete years.
It is the largest number h such that h articles published in 2011-2015 have at least h citations each.

For example
A journal with an h5-index of 50 will have at least 50 articles that were cited 50 or more times in the last 5 completed calendar years.

The h5-median for a publication is the median number of citations for the articles that make up its h5-index.

For example
In that same journal with the h5-index of 50 the h5-median will be the median number of citations for these 50 articles.


Finding the h5-index of a Particular Journal using Google Scholar Metrics
To find the h5-index for a particular journal
Open the link to Google Scholar Metrics.
Click on the magnifying glass icon in the top right of the screen to get a search box.

Type the title of the journal into the Google Scholar Metrics search box.



Clicking on the link to the h5 result will show you the 68 articles that have at least 68 citations detected by Google Scholar.
