[DCRM-L] Fwd: FW: Duplicate detection question

[Robert Maxwell]

My goodness, it would be nice to know what the magic words are on the table ... 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 LC's record #166872410.  I have merged RBN record #682917829 with #213384596, which also represents the Advance reading copy for the title "Airman".

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
