      Entries are codified as dictionaries whose keys are the
      different tags. For single line and singly occurring tags,
      the content is codified as a string. In the case of multiline
      or multiple key occurrences, the content is returned as a list
      of strings.
  
      Keyword arguments:
      bibliography_file -- ris filehandle
      mapping -- custom RIS tags mapping
      wok -- flag, Web of Knowledge format is used if True, otherwise
             Refman's RIS specifications are used.
