Thus, if a text is revised or modified, the resulting expression is considered to be a new expression, no matter how minor the modification may be.” “On a practical level, the degree to which bibliographic distinctions are made between variant expressions of a work will depend to some extent on the nature of the work itself, and on the anticipated needs of users.” Expression entity working group now formed 4/13/2006 Indiana Library Federation Annual9 Conference

- 21. How many records are affected? Average work has 1.5 manifestations 78% of works have a single manifestation ~99% of all works in WorldCat have seven manifestations or less ~30,000, or ~1% have more than 20 manifestations R.

- 25. Other cataloging changes Non-MARC environments Many already doing FRBR-like things Tend to have lots of programming support MARC environments Need more innovation from ILS vendors Catalogers used to looking at 1 record (well, 2 records) showing everything Need to provide complex relationships when necessary, hide when not Supporting legacy records will be complicated 4/13/2006 Indiana Library Federation Annual25 Conference

Notas do Editor
- <number> When we catalog, we start with an item we have at hand. From it we construct a bibliographic record that is intended to describe the manifestation, that is any copy held anywhere, so the record can be re-used by others in a shared cataloging environment. We also make authority records to control the way we identify works and expressions that are embodied in the manifestation we are describing, and that in turn may be linked to a name authority record for the person or corporate body that is responsible for creating the work or expression. In some integrated library systems this link between the bib and authority records is real, which also makes database maintenance and global update changes easier than when these links are not present.
- <number> Here’s a scenario for the future, where we would make use of authority records for works and expressions and do more linking directly at the authority record level for the classification and subject headings that are appropriate to the work. Those authority records would also be available to display for each linked bib record, and we could save cataloger’s time by not needing to classify and provide subject headings for all the manifestations of that same work/expression combination. For the location, call number for the items, We’d still need to cutter for the individual item or copy we were adding, but that would be a lot simpler than all the other subject cataloging work that is now done. The item information for inventory control, circulation, interlibrary loan, etc. would be entered as part of the holdings record and would reflect the call number for the copy held locally. I really like this model, but we need to experiment to see if this is best or perhaps there is a better implementation model for FRBR. This model will require some changes to the authority record – to include 65X’s for the subject headings – we already have a field for classification.
- <number> Here’s another scenario, where we could use the bib records for works and expressions, link the subjects or even use the 650’s in bib records as we can now, but somehow get our local systems to use the linked work/expression records as part of the displays when we view the manifestation records… This model, in my view is not really ideal… It would take a lot of work on the part of vendors to know how to display the linked work/expression records with the related bib records.
- <number> Here’s yet another scenario for the future, where we would use the MARC holdings record to capture all of the data elements (attributes) of the manifestation and items – that is, the physical characteristics – the physical media, publisher, distributor, manufacturer information relevant to the recording of the content. Attaching holdings records to authority records should not be a giant programming job, but many current integrated library systems avoid authority records altogether, which is a pity. The potential in the future for using the authority record and its ability to cluster the variant names given to things and to link to specific resources, opens up tremendous flexibility to meet future user demands. This might be particularly interesting for serials. The title of a serial is a controlled access point. Logically that would be in an authority record. But there is also the manifestation aspect of the physical format of any given serial and various attributes associated with the manifestation – its publisher, its numbering and dates, its physical medium (microform, digital online or a tangible digital object like a CD-ROM) and mode of issuance (e.g., successively issued or integrating resource) – we now put the manifestation information in bibliographic records And the item information may be in both bibliographic records or holdings in the MARC format and item records in local systems. If we had a clear way of identifying the attributes for a particular work/expression/ manifestation/item combination, we could theoretically combine all such combinations for the same work in a single record, and just display the needed elements as the application or user specified. There are many ways this could work.
- <number> Here’s yet another scenario – a variation from the last where we’d use the bib record again for the work/expression record…and the holdings record for manifestations and items…but this has the same drawbacks as Scenario C.. A lot of this depends on vendors to come up with system designs and for cataloging rules to be clear about needed entities and attributes and relationships – which brings us back to FRBR and cataloging rules.
