The cataloging cut-off point when it's either a new expression or a new work is captured in this slide from Barbara Tillett:
pg. 12 in http://www.ala.org/ala/mgrps/divs/alcts/confevents/past/ala/annual/04/Tillett.pdf Abridgements, revisions, translations are considered the same work but different expressions. Adaptations, change of genre, dramatizations, screenplays are considered different (but related) works. Expressions of works are considered to be "primary relationships" (Ch. 17 in RDA). Related works (work-to-work relationships) are covered in RDA Ch. 25. Related expressions are covered in RDA Ch. 26. There are some subtle cases where a full RDA treatment can sharpen the points we're making about relationships between entities. The following is an example of a specific expression-to-expression relationship (all expressions belong to the same work, even with their revisions): Resource described: Bond's Biology of fishes / Michael Barton. - Third edition - Belmont, CA : Thomson, (c)2007 Element: Related expression Value [using a structured description]: Biology of fishes / Carl E. Bond. - Second edition. - Fort Worth : Saunders College Publishing, (c)1996 Designator: Revision of In MARC, a generic 500 note field is used: 500 $a Rev. ed. of: Biology of fishes / Carl Bond. 2nd ed. 1996. RDA looks a lot bolder with its layered use of specific elements, although it does point out the tenuous nature of how works and expressions are strung together, since all revisions are expressions of the same work, yet different conventions may be used to string them together (identifiers, authorized access points, composite descriptions, structured descriptions). That three-part structure in RDA (element-value-designator) looks like it can open doors to better machine-processing of relationships, as opposed to burying relationship data in MARC 500 notes. That structure (element-value-designator) is a good pattern to understand early, because one can zip through the second half of RDA very quickly once the pattern is understood since the same structure is used for all relationships (person to work, work to work, person to corporate body, and so on). RDA can quickly become addictive I think, especially considering the staggering number of complex ways relationships are handled in MARC.

For example, I would definitely want all versions of say Pride and Prejudice listed as the same work, then have all the expressions of it listed below that, with the manifestations listed for each expression. ************************************** ************************************** Aleta Copeland, MLS Head of Technical Services Ouachita Parish Public Library 1800 Stubbs Ave. Monroe, LA 71201 318-327-1490 ex. 3015 From: Resource Description and Access / Resource Description and Access [mailto:RDA-L@LISTSERV.LAC-BAC.GC.CA] On Behalf Of runjuliet Sent: Thursday, April 07, 2011 11:37 AM To: RDA-L@LISTSERV.LAC-BAC.GC.CA Subject: Re: [RDA-L] FRBR Here's a nice visual representation of the Work/Expression/Manifestation/Item facets of the FRBR model I found via Twitter this morning: http://www.aurochs.org/frbr_example/frbr_example.html Only problem with it, to me, is that it doesn't link the novel, film, and screenplay together...
