Hello Michael. We deal with this situation in one of two ways. We can make a shapefile with one shape for each record. Alternatively, we can have a shapefile with one shape for each area depicted (7.5 minute topo quad, for example) which is joined to a database of all the records for that area. They both work, but one way or the other may be preferrable for some reason.

Hi, Anybody out there in library land display a spatial index in the catalog for a multi-sheet map (or series of maps)? For ex., Harvard sometimes depicts a bounding box for a single sheet [ http://id.lib.harvard.edu/fgdc/AFRICOVER_SM_MJTOWNS/catalog], or a box for a whole set of topos [http://id.lib.harvard.edu/alma/990044581400203941/catalog], but I want to depict--and, ideally, label--multiple boxes w/ the same record so that users looking at the record for a multi-sheet topo set can negotiate/navigate that set the way one used to do with print topo sheet indexes. Anybody seen this, or already doing it? Thank you.
