Isn't that perhaps a case of RDA 2.5.6 Designation of a Named Revision 
of an Edition, i.e. could it be the updated edition of the first edition?


If so, then I think the solution would be First edition, updated 
edition, because 2.5.6 comes after 2.5.2 according to D.1.1.
As far as I know, 2.5.6 isn't capitalized. The example Roads revised 
in 2.5.6.3 seems to be a mistake.

If you’re going to put in edition twice, it only makes sense to me to put 
“first edition, updated edition” as is updated edition of the first edition. 
“Updated edition, First edition” sounds like the 1st edition of the updated

My choice in Updated edition is from 2.5.2.2
Take designations of edition from the following sources (in order of 
preference):
a)
the same source as the title proper

The last part of 2.5.2.3
If more than one designation of edition is being recorded, record the 
statements in the order indicated by the sequence, layout, or typography of the 
statements on the source of information.

because these are located in two places, I would keep them separate. Remember 
the New Paris Principle Principle of Representation. It's represented 
differently in two places and should be transcribed as such.

I side with the minority on this one.

In 250 I would give the one s on the title page recto as peing the
prime source for the description.  The verso statement may be a
forgotten carry over from the first printing.  You could give it in a
quoted note I suppose, 500  $aFirst edition--Title page verso.

I say this even though 250 is now repeating. Having the First
edition in a 250 would be misleading I suspect.

While you might like 250 $a[First edition updated], it does not *say*
that.  It will be interesting to see what the next edition, if any, is
called.

To answer Mac's questions, there don't seem to have been unnumbered pages 
involved (except perhaps in the differing paginations of the bib record, 
Amazon, and Barnes  Noble).  There are lab sheets and tests in the second 
print, but not enough, I think, to account for the difference.  It's difficult 
to know what was added.

The OCLC number is 849655048.  The 250 is Second print -- this is what 
appears on the piece, so that's what I put in the 250.  I added a 500 Second 
print expanded from first printing.  Interestingly, the copyright had not 
changed, so I have two 264s.

Re: [RDA-L] Edition statements

2013-06-20 Thread Robert Maxwell
First, it's your judgment as to what constitutes an edition statement. If you 
think Second print is an edition statement you can record it as is. And in 
this case you have a good argument for the resource with the statement Seond 
print being a different edition.

If you're uncomfortable with that you can supply an edition statement, e.g. 
[Expanded edition]. 2.5.2.2c says you can take an edition statement from 
other sources aside from the resource itself, and other sources include your 
own brain. 2.5.2.2c permits this now; in addition the 2013 revision of RDA will 
add a clarification to 2.5.1.4: Optional addition. If a resource lacks an 
edition statement but is known to contain significant changes from other 
editions, supply an edition statement, if it is considered to be important for 
identification or access. (see 
http://www.rda-jsc.org/docs/6JSC-ALA-10-Sec-final.pdf).
