The GB_YR_MM.ZIP are the GeoBytes Newsletter which is published on
America Online by the GeoWorks Community on the service.  Currently
there are 9 that have been made.  Yon do need GeoWorks to view them,
they are not in PostScript due to incomatibilities with the PostScript
driver in GeoWorks.  You may exchange the newsletter with anybody you
choose. 

The Newsletters offer a great deal of information on GeoWorks.
