Karen,
My concern is about examples like the one I gave, although it may have
been imperfect. Assume that the preface is one that is considered
important enough to be noted in the catalog record, one that is
written by someone famous. You want to include an entry for that
preface under the name of Ms. Famous. It's a Work, so you need a Work
entry. (Also, you can't indicate a creator without having a Work
entity.) You want to indicate that the Work is a part of the
Manifestation along with the main text. Adding a new Expression-Work
unit is not a clear part/whole relationship (which is what Heidrun is
pointing out). And again I'm interested in how this would be displayed
to a user, how this set of relationships will be brought together in a
display. Perhaps one could treat this secondary "Work" as a related
manifestation? However, in FRBR structural terms, all Works are Works,
there are no "lesser Works," so there would be no difference between
this preface and an essay in a set of essays.
I don't see any problems here which couldn't be solved by sound
underlying data structures on the one hand and a proper design of the
display on the other.
Firstly, the system should be able to distinguish between an aggregate
work and an "ordinary" work. The whole/part relationship (from my
approach) would not be enough as ordinary works can have parts as well.
So there should be some sort of flag for an aggregate work, perhaps a
new attribute (aggregate / non-aggregate). By the way, if one were to
transform AACR/MARC data into FRBR/RDA data by means of algorithms, I
think there would be lots of indicators in the records (like 505 or
490/8XX) pointing out whether something is an aggregate or not.
Augmentations are different in that respect (you'd have a hard time
analyzing them mechanically, as probably the only information which
could be used are things like "edited with an introduction and notes by
..."). Therefore, for something like the augmented edition of Nabokov's
novel the flagging would be something which has to be done by the
cataloger who has decided to treat it as an aggregate work in the first
place.
The aggregate work, as it is a work, needs -among other things - a
preferred title of its own (core element in RDA). This might be
something like "Bend sinister (With additional materials)" (perhaps
also: "Nabokov, Vladimir, 1869-1922. Bend sinister (English. With
additional materials)", taking into account which expression of the
novel has been used of the aggreagte work. I'll have to think on that
some more).
There may be also a way to record the title of the introduction not
simply as "Introduction", but perhaps in a more meaningful way as
"Introduction [to Nabokov, Vladimir, 1869-1922. Bend sinister]" or some
such like. This would not be imperative, thpugh, as it can be made clear
in a different way as well: The environment of the work "Introduction"
(i.e. the aggregate work and/or the other works) can be displayed to the
user.
So, assuming the introduction in question is by a Ms Famous, and that's
why we want to bring it out in the catalog in the first place (by the
way, I'd rather like to think of catalogers as not using criteria like
this), and somebody is looking for all the works of Ms Famous, they
might get:
Famous Work #1
Famous Work #2
Introduction, in: Nabokov, Vladimir, 1869-1922. Bend sinister (With
additional materials)
Famous Work #3
In the case of augmentations, it might be useful to flag the predominant
work in the aggregate work somehow (Casey A. Mullin suggested that in
one of her posts in this thread). Then we'd also have the possibility to
present non-predominant works at the end of such a list, or perhaps
present them to the user only via a separate link (e.g. saying: "There
are also minor works of Ms Famous, such as: Introduction, in: Nabokov,
Vladimir, 1869-1922. Bend sinister (With additional materials). Show
minor works as well?"
Now if somebody looks for the work "Bend sinister" in an English
version, the system would look for the English expression (in my
diagram: E (W1)) and show all three manifestations linked to this. The
system would also note that one of the manifestations is an aggregate
one (there would not have to be an attribute "aggregate" on this level,
I believe, as the aggregation is obvious from the fact that more than
one expression is embodied). In this case, it would display further
information about its environment. The display might look somewhat like this
English version of: Nabokov, Vladimir, 1869-1922. Bend sinister
- Published: New York : Vintage International, 1990
- Published: Alexandria, Va. : Time-Life Books, 1981, c1947. Together
with: Ms Famous: Introduction. In: Nabokov, Vladimir, 1869-1922. Bend
sinister (With additional materials)
- Published: New York : H. Holt, [1947]
Would that be an answer to your concerns or have I misunderstood the
problem?
