Conoco’s tar sands development in South Texas / Michael W. Britton. (OCLC #898578225)
This title is about tar sands in South Texas. The authorized heading Oil sands can be subdivided geographically, and a geographic term is available for South Texas (South Texas), so we can assign the heading.
650 _0 ǂa Oil sands ǂz Texas, South.
I was surprised that OCLC’s Generate043 macro did not trigger based on this heading, so added the 043 for Texas by hand:
043 __ ǂa n-us-tx
I wonder which other headings are not being detected? Code for the macro is available from Connexion’s Tools -> Macros, and though it is over 2000 lines long, much of it is data, so it seems reasonable to read – maybe I’ll bring this one next time it’s my turn to host Code Club.
