In the UK we have a group called MAGIC (http://maths-magic.ac.uk/index.php) which runs graduate level courses in mathematics shared by video across 19 universities. In the early planning stages for that project (about 2005) I downloaded from MathSciNet lists of BiBTeX entries for all papers published by the participating universities in the previous decade, and sorted them by MSC code to get a systematic overview of the research activity across the network. That was quite a useful exercise.
