records with 040 dcrmb? If so, Richard should create a new record and in the

can't be Richard's problem. <o:p></o:p></span></p>

<p class=MsoNormal>Sorry that I sent such a long and unnecessarily detailed
question last week--I was too bound up in the book. Here it is briefly and
generically:<br>
<br>
I find out that book in hand is actually a 2nd ed., a page for page reprint,
with minor variations in text and illustrations, of the 1st ed. The two have
previously been treated by all agencies and authorities as a single edition. My
library has only this copy, which I have compared with the Google Books version
of the 1st ed.<br>
<br>
The holdings attached to the principal OCLC master record for the book
naturally represent a mixture of editions. Individual records (seen via IR or
institutional online catalog) are in some cases detailed enough to identify a
copy as 1st or 2nd ed., though copy-cataloging may mean, in many cases, that
the description doesn't actually apply to the copy; in other cases not enough
evidence is reported in the record.<br>
<br>
What to do?<br>
<br>
Case in point: Edmé-Sébastien Jeaurat, <i>Traité de perspective à l'usage des
artistes</i> (1750) OCLC 13455452.<br>
<br>
Many thanks --<br>
