[DCRM-L] Double leaves

[Matthew C. Haugen]

To follow up on Deborah's email: the DCRM task force encountered some
confusion about the definition and treatment of double plates in DCRM and
RDA, so we appreciate the feedback that might improve those definitions and
instructions.

I understand a double leaf to be sewn or tipped in with the fold at one of
the outer edges of the volume, functioning as one leaf because it cannot be
unfolded, with blank versos facing inside the fold that are not meant to be
seen. An entire volume may consist of double leaves, as in the case of
books in traditional East Asian format, or isolated double-leaf plates
bound in with a letterpress volume.

This seems to stand in contrast to:

-two leaves joined by a fold on an outer edge, but which are meant to be
opened by the binder or reader and to function as two leaves.

-two conjugate leaves sewn or tipped in with the fold at the inner margin,
which function as two leaves, much like any other conjugate pair of leaves
in the volume.

-a folded leaf, which may have one or more folds and which may open out to
other dimensions relative to the volume besides "double", but functions as
one leaf.

If a double leaf has been opened by a subsequent binder or owner, And this
is not apparent I imagine it would just be counted as two leaves without a
note, or if it is apparent it could be handled in a local note.

Somehow Deborah’s original question didn’t make it into my inbox (iCloud
has been behaving oddly recently), but I think she’s confusing two
different things.

Perhaps she’s thinking of the old problem of plates that can be bound
either as folding (attached on one edge and opening out) or “double” (sewn
through or pasted at a fold).  But those are a different kind of “double
leaf”.  I can’t recall ever seeing inserted plates printed on double leaves
unopened at top or fore-edge.

I’ll (un)happily join Richard in flogging the dead horse, though the animal
will never revive - the DCRM(B) definition of “plate” is like the rule to
describe all 1- and 2-page printings as “1 sheet”, written in the closest
thing to stone available in the electronic age.

Double leaves intended to function as such, and to be bound as here
described (whether or not the binding is correct in a given copy) are worth
this degree of special attention--they may be an issue point (=evidence of
variant manifestation), most likely as taken together with other evidence,
but still ...

Under caption "Beating Dead Horse": It simply isn't appropriate to refer to
letterpress leaves as "plates"; it's one of the fundamental principles of
bibliographical analysis. I would have  no trouble with "[2] folded
letterpress leaves" in the 300 field--where explicit "letterpress" acts as
a confirmation that the leaves are *not* plates. I'd go so far (self irony)
as to concede that *inserted* relief illustrations could be referred to as
plates (leaves or pages), even though they may have been printed in the
same operation. On the other hand, I suppose general use of "plates" makes
less of a demand on cataloger knowledge/judgment where a complete inventory
of physical bits is of principal concern.
