Rather than type separately all of the metadata elements that make up a citation, you may be able to get the Citation_Information from a bibligraphic database. For USGS publications, that database is the USGS Publications Warehouse. Here's how you can do this for USGS publications:
ofr | Open-File Report |
b | Bulletin |
pp | Professional Paper |
ds | Data Series |
sir | Scientific Investigations Report |
sim | Scientific Investigations Map |
i | I-map, various series names |
mf | MF-map, various series names |
cir | Circular |
fs | Fact Sheet |
