<div>
<div>Greetings, colleagues--</div>
<div><br>
</div>
<div>This latest thread on the horrors of record matching has led Jen Schaffner and me to get educated by internal experts about how OCLC's matching and de-duping (or not) process works. The short version: it's UNBELIEVABLY complex. So sorry, Margaret, but
your claim below is very much inaccurate.</div>
<div><br>
</div>
<div>I'll be sending more info anon summarizing what we've learned. Please stay tuned.</div>

<div>Best to all, Jackie</div>

<p class="MsoNormal"><span style="font-size:11pt; font-family:'Bookman Old Style',serif; color:rgb(31,73,125)">I encountered a similar problem about six months ago. I was creating individual records for various states of bookplates (oddly enough). The 245 fields
contained the same text, but each of the 300 fields had different information as to ink color and size. Within a week or so I discovered several of the records had been merged. When I called-out OCLC, I was told to include a fabricated edition statement to
prevent future merging! I instead opted to do what you folks have done, namely add other title information in brackets.
