[DCRM-L] Naming convention for statements of extent

Thu Mar 19 11:24:36 MDT 2009

Hi, everyone,
   It sure does seems as if DCRM is ahead of the curve on this, as spurred on by DJL (which I say because I had never heard this concept [the binary breakdown of the extent element] put forward until DJL explained her thinking at BSC in 1/09 and in subsequent e-mails; now it seems to me that this concept should have been in existence all along!). Anyway, I agree that the OCLC examples cloud the issue.  
   Beyond that, however, I still would like to see if it is possible to come up with a good, concise description of each part (or "half") of the extent element (because it has come up for us in DCRM(M), as you'll recall, with the "describe folded ..." etc. issue).  And in reviewing Nina's offerings, I am "glomming on" to the word "constituent", as found in the ISBD definition.
   Here's my thinking. First of all, the 2nd half is really not about "illustrative matter", but about inserted material beyond (or, outside of [or, auxiliary to]) the "text block" (which is the 1st half). Unfortunately, the term "text block" is book- or text-oriented, so it would be nice to capture that concept without using such terminology. (Remember that for music materials [just as an example], the main content of the first half of this element is probably most often "graphic" (meaning, notation), while the inserted material might itself more often include textual matter (e.g., contents, title lists, music instructions, and the like) along with ills. or more notation.
   So, in consulting my nearest dictionary (the RH _Amer Coll Dict_ [1959]), I find that "constituent" has two relevant descriptions: 1. "serving to make up a thing; component ..." ; 3. "a constituent element, material, etc., ; a component". So, it would seem as if either "constituent" or "component" could be used towards defining these halves. My thinking is that the concept of "text block" could considered the "primary constituent (or component)" and any inserted material could be the "secondary constituent (or component)". If these terms were used, they would, of course, need to be carefully explained. (In this scenario, I would think that "accompanying material" would be a "tertiary constituent [or component]", but that could start getting confusing in cases where there's no intervening "secondary".)  Anyway, I'm not trying to suggest that this is an "elegant" solution, but am offering it as another way of looking at things, towards DJL's request to come up with formal language for these halves.

I'm not sure this is right, Nina, although it's somewhat confused. I looked at OCLC and MARC 21, and the "statement of illustrative matter" seems to refers to the 300‡b. What clouds the issue, and something I think is downright wrong, is the second example in MARC 21 in the text Nina refers to.

When the statement of pagination and of illustrative matter are combined, they are both recorded in a single subfield $a.
300 ## $a74 p. of ill., 15 p. ;$c28 cm.
300 ## $a27 leaves of plates, 4 p. ;$c31 cm. 

Where, I ask you, does the "statement of illustrative matter" appear in the second example? It is perhaps implied by the use of "plates," but the absence of "‡b ill." belies the implication. In fact, I think MARC is just plain wrong in its confusion of extent and description of physical details. Or perhaps it's that DCRM is ahead of the curve on this one.

This sounds like a job for Controlled Vocabularies! Ha ha

OCLC calls the first part "Statement of pagination" and the remainder
"Statement of illustrative matter" and so does MARC21:

	When the statement of pagination and of illustrative matter are
combined, they are both recorded in a single subfield $a.

	300	$a74 p. of ill., 15 p. ;$c28 cm. 

	300	$a27 leaves of plates, 4 p. ;$c31 cm. 

 ISBD's definition of 300:

	The name of the specific type of material to which the item
belongs, and an indication of the number of pieces in an item, the
number of constituent parts (e.g. pages, frames) of an item, etc.,
consisting of one physical entity, and, for items with a playing
time, the duration of the item.

But that doesn't go beyond "constituent parts".

How helpful is that? Not very, I'm afraid. 

Nina

I've twisted my tongue for years trying to use formal language to make
distinctions between the two parts that together make up the statement
of extent. I'm hoping this community can establish a convention for
referring to these two parts, and throw this out as a suggestion. 

*         The "statement of text" = the first sub-element of the
statement of extent, comprising the extent of letterpress leaves (or
plates, if the book is wholly or primarily plates as in 5B1.4)  

*         The "statement of plates" = second sub-element of the
statement of extent, comprising the extent of plates

It's imperfect, because what's on the letterpress may not be text, but I
can't think of anything better. 5B1.4 itself provides a precedent: "If
the leaves are all or chiefly non-letterpress, record them as leaves or
pages of text  ..."
