Subject Subdivisions

Geographic subdivisions $$z

Geographic subdivisions can be useful when we want to specify the geographic location aspect of a topic. We will use an example to illustrate how to structure a geographic subdivision into a topical heading: I am cataloging an item about Goldwork made in Dresden, Germany during the 17th century.  
Make sure I can subdivide "Goldwork" by a geographic subheading. I find this in the 008 of the Subject Authority Record (SAR) for the term, look for "Direct/Indirect Geographic Subdivision" see the MARC guidelines for further details, you should see one of these:

# - Not subdivided geographically
d - Subdivided geographically, direct
i - Subdivided geographically, indirect
n- Not applicable

This is what it looks like via WMS/OCLC :

Finding "i" for indirect entry means I need to put the larger geographic in before the more specific one I'd like to put in the subject string. If it were "d" for direct, I could enter Dresden directly after the topic. If you see a "#" and therefore canNOT subdivide geographically, we will cover that with our next example.
Now I need to find the indirect form for Dresden. I searched for "Dresden" in WMS and found the heading "Dresden (Germany)". You will note that like many cities, the 151 includes the country:

Sadly, that isn't what we are looking for. Scroll down to field 781 you will find the geographic subdivision form  (guidelines for the 781 field):

Ta Da! So now I know my heading can be:

650_0 $$a Goldwork $$z Germany $$z Dresden $$x History $$y 17th century.

How to proceed if you canNOT subdivide geographically

In this example, we want to express a scholarly discussion around many decades and examples of European art made using "rubbish" or rather "Refuse and rufuse disposal in art." This time, we look at the SAR in Alma. And in Alma's SAR view of the 008 you have to count for the 06 place (7th figure because the first place is the 00 place), and we find the "#" for prohibiting geographic subdivision:

In this case, you must find alternative ways to express Eurpoe in your subject headings. Looking up the same topic of "Refuse and rufuse disposal" without "in art" did allow for geographic subdivisions:


You can also consider whether the adding "Art, European" or a similar heading more specific to the medium or genre being discussed, such as "Pottery, European" or "Watercolor painting, European" would be appropriate for the item in hand.
