My goodness, it would be nice to know what the magic words are on the table
Š Anybody have any idea how to access this table?

Heads up on defensive cataloging: Apparently the merge blocking depends on a
table of specific phrases, etc. If the contents of the 250 don't match
anything in the table, the record is susceptible to merging.

Hi Cynthia,

We have a question about the duplicate detection software.  We understood
from the webinar that entering a 250 field would probably protect a record
from being merged.  We recently received a large collection of "advance
reading copies" which we are cataloging as originals with 250 fields,
usually deriving from an existing record for the published form of the book.
Examples:

#673622653
#682903749

Today while working on our November ftp of records from our catalog to OCLC,
I noticed that at least 2 of these have now been merged with the published
copy and the OCLC # we generated has been moved to MARC 019.  Examples:

#166872410
#61881209

Any idea why some of these are merging and others not?  Should we still be
treating this type of material as original?  The 250 statements vary
somewhat (Advance reader's ed, Advance uncorr. proof).  Is there another
field we should be using to indicate that this type of material should not
merge?

Thanks!

Hi Shanna,

Thanks for your quick fix on these.  Here is another example of the 250
field we are entering for this project:

250  Advance reading copy

Hi, Gretchen,

Your understanding from the webinar is correct.  The edition statements you
added to the records should have been enough to prevent them from being
merged, and I have had your records recovered.

Your message allowed us to identify another record that was also incorrectly
merged to LC¹s record #166872410.  I have merged RBN record #682917829 with
#213384596, which also represents the Advance reading copy for the title
³Airman².

Our DDR team has added these specific edition statements to the tables so
that records with this type of edition statement are no longer merged.

Thank you for bringing these to our attention.  It is feedback such as this
that allows us to better refine the matching algorithms used in the DDR
process.

Please let me know if you have any questions, or if I can be of further
assistance.

Thank you,
Shanna
