I'm not familiar with MARC, but I'm working on something similar for
historic topo maps. Basically, the user enables an index of polygons that
show the location of each map. The polygons are color-coded depending on
the scale of the topo (15', 30', etc). The information baloon in Google
Earth has a link for the various years that are available and clicking on
one of the years will overlay that map onto Google Earth. Here's a couple
screenshots of what it looks like in Google Earth.

In my case, I'm generating the polygons automatically from the actual
georeferenced maps using a program called Global Mapper. I then export the
polygons as a SHP/DBF file, do a little magic on the DBF file to generate
the hyperlinks and other info I want to be in the Goodle Earth Info Baloon,
then convert the SHP/DBF file to KML using a program called MapWindow (free)
with a plugin called Shape2Earth (not free).
I'm not familiar with MARC, but assume the MARC 34 data is some kind of
georeferencing information?? Basically, if you can get your lat/lon info,
hyperlink info, Map Name, etc, into a spreadsheet or CSV format somehow,
then should be a way to turn that data into KML without too much fuss. It
would probably be MUCH easier to associate the data with a Placemark (single
point) in Google Earth, vs. a polygon.
As for creating your MARC tags automatically, that's something I can't help
you with.
