duplicate detection in Extended Approval Plan

[Michael Kreyche <mkreyche at kent dot edu>]

I am looking at our Extended Approval Plan interface and would like to 
compare experiences with other libraries that use it. The duplicate 
detection doesn't seem to be working quite the way folks here thought it 
was and not as well as we think it should.

When we load our brief bibs and order records (from YBP), up to 30% 
percent of them are flagged as potential duplicates while very few of 
them actually are. To take a recent example, 56 records loaded, 16 
flagged as duplicates, only one actual duplicate. How does this compare 
with your experience?

Looking at the report, about half the records flagged as potential 
duplicates are by "series key" and the other half by "title" (not title 
key as folks here believed). Are these the criteria other libraries are 
using?

I am wondering why in the world the software is checking on the series 
key at all--that seems a good way to flag a false duplicate every time! 
I can see in the load table where the title checking is enabled, but I 
don't see anything about the series key.

I welcome any observations.

Thanks,
Mike
