Google Scholar have released journal metrics data for 2014.
Google Scholar Metrics are a tool that can help to identify influential academic journals.
They provide lists of the top 100 journals according to their h5-Index, in 9 languages. For English language journals, you can also view the top ranked 20 journals by subject category.
Journals are ranked by their h5-index: a variation on the h-index which provides an indication of productivity (the number of papers published in the last 5 years) and citation impact (the number of times those papers have been cited in the last 5 years). A journal with an h5 index of 300 would have published 300 papers in 2010-14 with at least 300 citations each.
For a more complete picture of journal impact, we recommend using Google Scholar Metrics alongside other journal ranking tools such as Journal Citation Reports from Web of Science, and Scimago Journal Rank (based on Scopus citation data).
More information on using these can be found on the Library webpages
