Journal Citation Metrics

Google has released new rankings of journal citations (using the H5 index. “The h5-index, h5-core, and h5-median of a publication are, respectively, the h-index, h-core, and h-median of only those of its articles that were published in the last five complete calendar years.” The h-index is “the largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has the h-index of 3.”).

Two areas of interest to readers of this blog include:

Urban Studies & Planning



While the rankings do not align exactly with what you might get from other sources (in particular classification of journal articles into particular venues), it is not totally surprising. It would be nice to go deeper with this than the top 20.

The index itself is biased toward large journals with lots of articles, assuming quality is fixed, as it is easier to have 50 papers cited 50 times if you publish 50 papers than if you publish 40 papers.
