  You've just encountered an obsolete piece of data -- HGML stands for Human
  Gene Mapping Library, a database that used to be at Yale and was succeeded
  by GDB.  Several years ago, when NLM started entering cross-references to
  sequence data bases, the HGML literature references were mapped to Medline
  citations.  Since this type of change to Medline will be done in batch mode, the
  references probably will stay in Medline until the next update cycle which
  will be in November.  Til then, about the only information the HGML tag 
  communicates is that the paper referred in some way to a gene map.
