New Fields & Facets in Library Catalogs
Chicken or the egg?
Incomplete recall and user expectations
Retrospective conversion
“I got tired of cataloging
for my grandchildren.”
Humpty Dumpty Problem
 
Too Many Options
 
Music-Specific Scope in Primo
Primo Central Index (PCI)
integration problem
Computational Constraints
No true exploratory search or browse
in Primo
Incomplete recall in most cases
Computational Constraints
Static facets
Enumerated list (ca. 500 terms)
Counts and displays all results
https://knowledge.exlibrisgroup.com/Primo/Product_Documentation/Back_Office_Guide/100Facets
Computational Constraints
Dynamic facets
Open-ended list
Displays top 20* terms
from records ranked in
top 200* results
Displays count (and
retrieves) matching
records from top 50,000
results
*Default values; can be increased
somewhat, but trade-off on
performance
Constraints on Manipulation
Norm Rules in Primo Back Office
Browser-based GUI interface with hard-coded
conditions and transformations
There’s no way to move just one rule of a group
to a group in another rule set.
OTB conditions/transformations can’t always
target really specific data strings.
Some transformations are broken, which
requires creative multi-step workarounds.
Primo Indexing Limitations
MARC field-specific search and browse
These features have garnered some interest with
our members
We’re limited to 50 local search indexes in Primo,
and none will pull in PCI resources.  OTB indexes
have fields grouped together.
Browse indexes are
significantly more limited
in number and data
source.
Lateral Linking Limitations
Using lateral links could provide an
alternative to facets, but...
Limited to 9 locally-defined fields.
Functionality isn’t 
quite
 the same as faceting
(executes new search rather than filtering
current result set)
Moving (and Looking) Forward
We’ve been very successful in using new
metadata fields to set up facets for Alliance
member institutions’ use.
As time goes on and these newer fields are
more widely used, the facets will prove
more accurate and more helpful.
Stats on field use are available at
http://experimental.worldcat.org/marcusage/
We can review facet
use with Primo
Analytics.
Moving (and Looking) Forward
We’re investigating additional facets on
request.
Specific relationship designators
Would a general “relationship” facet be useful?
We have lots of questions about Primo VE!
Will Primo normalization rules still exist?
Will Primo VE have the flexibility of Primo
for translating metadata for faceting?
If not, we’ll need to advocate for
this.

Slide Note

New LC Fields/Subfields:  In recent years, many new fields and subfields have been introduced into MARC21 that can prove useful when leveraged in a faceted discovery interface.  In this presentation, we will look at several of these, describing how we incorporated them into Primo and discussing the challenges we encountered.
