SCImago Journal and Country Rank

News of a new journal ranking site from the SCImago research group at the University of Granada. Described as follows:
The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.). These indicators could be used to assess and analyze scientific domains.

This platform takes its name from the SCImago Journal Rank (SJR) indicatorpdf, developed by SCImago from the widely known algorithm Google PageRank™. This indicator shows the visibility of the journals contained in the Scopus® database from 1996.

A natural question for me, then, is: How does Information Research show up in this new ranking? So, I took the journals that are similar to Information Research, in that they are not 'niche' journals, but publish widely across information science, information management, librarianship, etc., from ISI's Journal Citation Reports and then gathered the data from SCImago. To reduce the effort of creating a table (not as easy in Blogger as it is in Free-Conversant) I have taken the top 10 journals from the list:

Journal                h-index SJR   cites/doc     JIF

Info & Mgt             29     0.069    3.65     2.119

Journal of ASIST       27     0.068    2.48     1.555

Info Pro & Mgt         27     0.058    2.11     1.546

J of Doc               23     0.058    1.61     1.439

Info Research          12     0.053    1.77     0.870

Lib & Info Sci Res     14     0.053    1.26     1.059

Int J Info Mgt         18     0.051    1.55     0.754

Lib Qly                14     0.051    1.23     0.528

J Info Sci             17     0.051    1.01     0.852

Lib Trends             14     0.050    0.85     0.545


The use of the h-index is well known in the bibliometrics fraternity and is normally used to measure the productivity and impact of an individual scholar. One of its problems, particularly significant in ranking journals, is that the longer the period in which the scholar (journal) has been active, the more likely it is that the scholar (journal) will receive a high h-index, so it's usefulness here may be limited. However, it is interesting to see that Information Research has an h-index of 12, while older journals have lower measures.

The SJR measure is explained as,
...an indicator that expresses the number of connections that a journal receives through the citation of its documents divided between the total of documents published in the year selected by the publication, weighted according to the amount of incoming and outgoing connections of the sources.

The 'cites/doc' measure is based the number of citations received in the previous four years and the total number of documents published in 2006.

JIF is the ISI Journal Impact Factor.

  3. Many institutions limit access to their online information. Making this information available will be an asset to all.

  7. My friend and I were recently talking about the prevalence of technology in our day to day lives. Reading this post makes me think back to that discussion we had, and just how inseparable from electronics we have all become.


    I don't mean this in a bad way, of course! Societal concerns aside... I just hope that as the price of memory falls, the possibility of downloading our brains onto a digital medium becomes a true reality. It's one of the things I really wish I could encounter in my lifetime.
