RE: Table of Contents Enrichment and Authority Control

["Kespohl, Robin A." <KespohlR@xxxxxxxxxx>]

Here at the MOBIUS libraries we receive TOC enriched records from BNA with the 970$f (Indexable (inverted) person name author or editor).  Blackwell's description of the process is: "Blackwell's inverts personal author's names and applies authority control to reduce variant author forms, to bring the forms into conformance with LC rules and practices, and to provide the current form when available in LC's name authority file."

The catch 22 is that although the form of the name may match the LC authority file, there is no subfielding in the $f. If these headings are indexed in the author index and the form is the same, i.e. Twain, Mark, 1835-1910, the patron retrieves one list containing those with $d and those without (that's the good news).  The bad news is that the heading without the $d will be in the headings reports as a Heading Used for the First Time or if Automatic Authority Control Processing is enabled as a Near Match. 

If the $d is added manually then the dates are no longer part of the indexed $f and the patron retrieves two lists:  Twain, Mark and Twain, Mark, 1835-1910.

Our libraries have made two different decisions regarding the problem.  Some libraries have chosen not to index the $f in the author index but to index in keyword only.  Other libraries have chosen to index the $f in the author index and the keyword and to be very careful when doing authority control to correct form but not to add subfielding.  

Hope I haven't confused you even more.

Am I right that if you don't worry about authorized headings (you have my 
sympathy), and a patron does an "unauthorized" search, this user will only 
get what's in the catalog under the unauthorized name and not other things 
under the same person with a "different" name?
In other words: what are the implications for not doing authority work? I 
also assume that this kind of authority work is not done by any companies 
that offer usual authority work, like Marcive, etc.

Just some thoughts,

Michaela
