The names of the files in this directory are based on the bibtex keys in the bibtex file in the LCS bibliography. The key is the text after the { and before the , on the first line. For example, here's the bibtex entry for Hercog1998a:

@MastersThesis{Hercog1998a,
  author =       "Luis Miramontes Hercog",
  title =        "{Hand-eye coordination: An evolutionary approach}",
  school =       "Department of Artificial Intelligence. University of
                 Edinburgh",
  year =         "1998",
  keywords =     "LCS",
}

The papers are mostly gzipped postscript, but a few are in PDF.
