Subject: two confusing LCGFT headings

Can anyone help elucidate the difference between the two LCGFT headings
"Geodatabases" and "Geospatial data"? It's not at all clear from the
notes in the authority file. LC practice suggests that the former
heading (which has appeared only a couple of times) tends to be used for
shapefiles and the like while the latter (which is commoner) is more
often used for raster data (mostly georeferenced Sanborn maps). But that
can't really be true since the LCGFT headings "Raster data" and "Vector
data" both have 555s referring to "Geospatial data" (but not
"Geodatabases").

I've asked the folks at LC but haven't yet gotten an answer.

What I'd like to know most of all is what the correct LCGFT heading
would be for the shapefiles wthe University of Chicago Library has
acquired from various sources. There are hardly any recent LC records
for this sort of data set. (A larger issue is whether cataloging records
are an appropriate form of metadata for geospatial data at all--but,
hey, they're the kind of metadata that libraries are used to producing
...)

Many thanks.
