Hello all, Here is the documentation on the Marc *034* field for the coordinates. They seem to all use leading zeroes so that there is a consistency in the number of digits used for all of the W, E, S, N values. This is no doubt for ease of machine manipulation. But I do remember when I input the *255 values*, I did not always include leading zeroes; I made sure that all of the values had the same number of digits, though. So I think I agree with Tim. Cheers, and Happy New Year! Louise Ratliff Retired UCLA map cataloger *$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 $g always appear together. The coordinates may be recorded in the form *hdddmmss* (hemisphere-degrees-minutes-seconds), however, other forms are also allowed, such as decimal degrees. The subelements are each right justified and unused positions contain zeros. Examples in *degrees/minutes/seconds*: *hdddmmss* (hemisphere-degrees-minutes-seconds): *034* *1#**$a*a*$b*22000000*$d*W1800000*$e*E1800000*$f*N0840000*$g*S0700000 *034* *1#**$a*a*$b*253440*$d*E0790000*$e*E0860000*$f*N0200000*$g*N0120000 *[The above two examples illustrate records for flat maps or flat maps in atlases.]* Example in *decimal degrees*: *hddd.dddddd* (hemisphere-degrees.decimal degrees): *034* *1#**$a*a*$d*E079.533265*$e*E086.216635*$f*S012.583377*$g*S020.419532 Example in *decimal degrees*: *+-ddd.dddddd* (hemisphere[+/-]-degrees.decimal degrees) (“+” for N and E, “-“ for S and W; the plus sign is optional): *034* *1#**$a*a*$d*+079.533265*$e*+086.216635*$f*-012.583377*$g*-020.419532 Example without the optional plus sign: *034* *1#**$a*a*$d*079.533265*$e*086.216635*$f*-012.583377*$g*-020.419532 Example in *decimal minutes*: *hdddmm.mmmm* (hemisphere-degrees-minutes.decimal minutes): *034* *1#**$a*a*$d*E07932.5332*$e*E08607.4478*$f*S01235.5421*$g*S02028.9704 Example in *decimal seconds*: *hdddmmss.sss* (hemisphere-degrees-minutes-seconds.decimal seconds): *034* *1#**$a*a*$d*E0793235.575*$e*E0860727.350*$f*S0123536.895*$g* S0202858.125 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 $g, respectively). *034* *1#**$a*a*$b*75000*$d*W0950500*$e*W0950500*$f*N0303000*$g*N0303000 *034* *1#**$a*a*$d*W119.697222*$e*W119.697222*$f*N034.420833*$g*N034.420833 *034* *1#**$a*a*$d*-119.697222*$e*-119.697222*$f*+034.420833*$g*+034.420833 *034* *1#**$a*a*$d*W11941.833333*$e*W11941.833333*$f*N03425.250000*$g* N03425.250000 *034* *0#**$d*W0735848*$e*W0735848*$f*N0404554*$g*N0404554 *[Coordinates of Carnegie Hall, a concert venue depicted in an image.]* On Mon, Dec 20, 2021 at 7:57 AM Angela R Cope <[log in to unmask]> wrote: > 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?
