Query: An insight into the importance of national university rankings in an
  international context: The case of the I-UGR Rankings of Spanish universities   The great importance international rankings have achieved in the research
policy arena warns against many threats consequence of the flaws and
shortcomings these tools present. One of them has to do with the inability to
accurately represent national university systems as their original purpose is
only to rank world-class universities. Another one has to do with the lack of
representativeness of universities' disciplinary profiles as they usually
provide a unique table. Although some rankings offer a great coverage and
others offer league tables by fields, no international ranking does both. In
order to surpass such limitation from a research policy viewpoint, this paper
analyzes the possibility of using national rankings in order to complement
international rankings. For this, we analyze the Spanish university system as a
study case presenting the I-UGR Rankings for Spanish universities by fields and
subfields. Then, we compare their results with those obtained by the Shanghai
Ranking, the QS Ranking, the Leiden Ranking and the NTU Ranking, as they all
have basic common grounds which allow such comparison. We conclude that it is
advisable to use national rankings in order to complement international
rankings, however we observe that this must be done with certain caution as
they differ on the methodology employed as well as on the construction of the
fields.
