About five years ago, in 2011, Prof. Volli Kalm wrote a short review of the bibliometrical analysis of Oil Shale, an Estonian journal covering all aspects of science and technology related to oil shale. Now, a few years later, it would be good to take another, more up-to-date look at Oil Shale and its bibliometrical data to see how the journal’s role and pertinent information have changed since 2011.
   In the last years, a lot has changed in bibliometrics and scientometrics. Biblio­metrical analysis is still an everyday part of science and scientific analysis just as a peer review, but the range of bibliometrical indicators has widened from superficial indicators like citation count and h-index to more specific indicators like field-normalized citation rate and journal quartile score. These new indicators enable us to have a deeper insight into a journal’s impact within its own field.
   Strong competition between Thomson Reuters Web of Science and Elsevier Scopus has made them two of the largest, most reliable and prestigious data­bases in the world. There is little doubt about the quality of information in these databases. The data contained may sometimes be different but this does not affect their overall value. Although criticized by some users for being more useful for those fields of research whose numbers of citations are higher, both have followed a fair and equal policy towards all of them.
   This short review of the bibliometrical indicators of Oil Shale was made using data from the following databases: Web of Science Core Collection (WoS), Journal Citation Reports (JCP), Scopus and SCImago. Data was taken on the 2nd of November 2014.
