$g - Coordinates - southernmost latitude
Subfields $d, $e, $f, and $g individually identify the four coordinates of the item. Subfield $d represents the westernmost extent of the item; subfield $e, the easternmost extent; subfield $f, the northernmost extent; and subfield $g, the southernmost extent. The abbreviations for the hemispheres are: N = North, S = South, E = East, W = West.
Subfields $d, $e, $f, and $g always appear together. The coordinates may be recorded in the form hdddmmss (hemisphere-degrees-minutes-seconds), however, other forms are also allowed, such as decimal degrees. The subelements are each right justified and unused positions contain zeros.
Examples in degrees/minutes/seconds: hdddmmss (hemisphere-degrees-minutes-seconds):

Example in decimal degrees: +-ddd.dddddd (hemisphere[+/-]-degrees.decimal degrees) (“+” for N and E, “-“ for S and W; the plus sign is optional):

Example in decimal minutes: hdddmm.mmmm (hemisphere-degrees-minutes.decimal minutes):

If the coordinates are given in terms of a center point rather than outside limits, the longitude and latitude which form the central axis are recorded twice (in subfields $d and $e and in $f and $g, respectively).

Extent Update
1) The base map choices have been added (lower right)
2) Can anyone look at the MARC layouts in Extent and give feedback? Do any of the formats require MARC leading zeros?3) Coordinates must be entered in order of W, E, N ,S to validate, so something like -100,-90,36,28 (when you click on "coordinates," the search button says not valid but once you enter in coordinates such as this example, the buttons refreshes to valid)
Anything else??
