Downloading all the torrent files:

  mkdir torrents
  for i in {000..689}; do curl -sS "http://gen.lib.rus.ec/scimag/repository_torrent/sm_${i}00000-${i}99999.torrent" -o "torrents/sm_${i}00000-${i}99999.torrent" -m 30; done

...which themselves take up about 75 MB, so here is the full collection of torrent files for your convenience:

And a torrent that is basically equivalent to that file, thanks to the below commenter:

Each torrent appears to index 100 zip files (about 800 MB each), each of which presumably contains 1000... journal articles? I don't know. The seed isn't blazing fast, so it will be a bit before I can pull out a random zip file from this randomly selected torrent and inspect it.
