</font><br></span><br>Hi Cynthia,<br>
<br>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:<br>
<br>#673622653<br>#682903749<br><br>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:<br>
<br>#166872410<br>#61881209<br><br>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?<br>
<br>Thanks!<br><font color="#888888"><br>Gretchen Yealy<br>Brown University Library<br><br></font><br>----------<br><span><font color="#888">From: <b>Yealy, Gretchen</b> <span dir="ltr"><<a href="mailto:gretchen_yealy@brown.edu" target="_blank">gretchen_yealy@brown.edu</a>></span><br>
