IFLA study group report: Functional Requirements
for Bibliographic Records |
|
Bibliographic model independent of cataloging
rules |
|
Clusters bibliographic items into a four-level
structure |
|
Work |
|
Expression |
|
Manifestation |
|
Item |
|
|
|
|
|
|
|
|
|
Potential to improve: |
|
Cataloging |
|
Discovery |
|
Delivery |
|
By |
|
Bringing versions of works together |
|
Showing relationships of various kinds |
|
Enabling users to navigate to level of interest |
|
|
|
|
|
|
Subsets |
|
By library, region |
|
Example/problem sets |
|
Shakespeare, the Bible |
|
Humphry Clinker |
|
1,000 random works |
|
By genre |
|
Dissertations |
|
Fiction |
|
Whole file, 47 million bibliographic records |
|
|
|
|
|
Concentrating on work-level |
|
Problems with expression-level clusters |
|
Efficient, maintainable, understandable |
|
Few, if any, false matches with correct
cataloging |
|
Err on the side of missed matches |
|
Some accommodation of frequent variants |
|
Compare with manually clustered |
|
|
|
|
|
A key is generated for each record |
|
Extract author, title |
|
Look up in NACO authority file |
|
Added entry information as needed |
|
Form a key from bibliographic record |
|
Author, title, added entry information |
|
These can be sorted, compared |
|
|
|
|
|
|
|
Many (17%) records do not have |
|
Author main-entry |
|
Uniform title |
|
In general these can not be matched |
|
Look at added entries |
|
Information at the expression and manifestation
levels |
|
Handled separately |
|
180,000 clusters involving ~400,000 records |

Employs work clusters in a prototype system for
searching and browsing bibliographic records for fiction |
|
Indexes records at the work level and organizes
displays by work and expression (primarily language) |
|
Includes records for textual items; additional
modes of expression (moving image, sound) to be added later |

Enhancement of (fiction) records at work level |
|
with elements from records within the work
cluster (e.g., summaries, genre terms, subject headings, class numbers) |
|
with external data (e.g., literary prizes,
prequels/sequels, reviews) |

Identifying appropriate bibliographic data for
systematically grouping or differentiating works and expressions |
