12. Improving Displays of Bibliographic Data
Title (245)
Changes made:
•Added 245 subfield c
•Put 245 subfields in order they are cataloged in, rather than in a
specified order
•Removed everything from subfield h for sound recordings except
for forward slash (/)
13. Improving Displays of Bibliographic Data
Controlled Names & Name/Titles (1XX/240, 7XX)
Changes made:
•Placed 1XX with 240
•Placed 1XX/240 with name/title 7XXs
•Line breaks between name/titles to make it easier to read
•Separated name-only 7XXs into their own list
•Included all subfields in proper order
14. Improving Displays of Bibliographic Data
Results Page Title/Author
Changes made:
•Included (nearly) complete 245 in title line
•Removed everything from subfield h except for forward slash (/)
•If item is a sound recording with a 245 $c, it no longer includes
“by” line
•Added 511 performer note instead of 7XXs
15. Improving Displays of Bibliographic Data
Results Page Author
Changes made:
•Consolidated author entries
16. Improving Displays of Bibliographic Data
Results Page Item Format
Changes made:
•Replaced generic “sound disc” format with more specific CD or LP
designation
•Modified icon to reflect proper format
•Removed “Literary form” from sound recordings
17. Improving Displays of Bibliographic Data
Why This Matters
1) This is not an attempt to promote Koha.
2) Our data is the most important part of our
catalog. We need to have the tools to modify
displays in creative ways based on our
familiarity with our own data.
3) If given the tools, we need to then actually use
them.
18. Music Discovery Beyond
MARC
Benefits and challenges of domain-driven
functionality outside the ―silo‖

Libraries
19. Music Discovery at Stanford
SearchWorks
◦ Canonical catalog since September 2010
◦ Blacklight implementation
◦ Feature rollouts to date largely domainneutral
◦ ―Music view‖ in preliminary development
19
20. Music Discovery at Stanford
Features that benefit all domains, but were
prompted by music-specific use cases
◦ Name-title searching
Source: http://searchworks.stanford.edu
20
21. Music Discovery at Stanford
Features that benefit all domains, but
were prompted by music-specific use
cases
◦ Better 7xx labeling (based on 2nd indicator)
―Related work‖ vs. ―Included work‖
Source: http://searchworks.stanford.edu
21
22. Music Discovery at Stanford
Features that benefit all domains, but
were prompted by music-specific use
cases
◦ Date slider and enhanced date display
(i.e., not just ―Date1‖)
22
23. Music Discovery at Stanford
Emerging metadata ecosystem no longer
limited to MARC
◦ Metadata for digital objects and collections ―flows
in‖ through a separate pipeline
Mapping decisions
Item vs. collection-level access
Harmonization with MARC metadata
Conversion to MODS (for storage)
Remediation
Conversion to SOLR indexes
◦ MARC-based domain-driven functionality
complicated by the presence of native nonMARC metadata
Not really a new problem
Doesn’t mean MARC should (continue to) be glossed
over
23
24. Alternative Paths to
Knowledge
Not just beyond MARC, but beyond the
―catalog‖ (as we know it)
◦ Locally stored and maintained metadata an
obsolescent notion
Shared ILSes
OCLC Worldshare Management Services (―the
cloud‖)
◦ Pie-in-the-sky vision: Catalog (discovery
layer) no longer merely a (slick, sexy)
inventory of a library’s holdings (whether
owned or licensed), but a true knowledge tool
◦ How do we realize this?
24
25. Alternative Paths to
Knowledge
Linked Data
◦ Links can be leveraged in both directions
In: enhanced metadata, displayed in context
Out: links to external sites for further exploration of
a person, place, topic…
Can (must) be applied judiciously!
◦ Risk: the larger the web of data, the fewer
assumptions can be made about a results
set, and thus the less confidently algorithms
can be applied
◦ But, links and external content can be
activated using similar algorithms to those
that activate special display rules, facets, etc.
25
26. Linked Data—Music use
cases
◦ MusicBrainz
Enhanced track-level metadata (for popular
music, especially)
Robust relationships between works, recordings
26
28. Linked Data—Music use
cases
◦ Opening Night! Opera & Oratorio
Premieres
Rich data on the works themselves (e.g., date and location
of premiere), with live links to SearchWorks
28
31. Linked Data—Music use
cases
◦ Linked Jazz
Relationships between performers (collaborators, mentors)
Could prompt a user to expand a results set based on a
performers personal network (―More like this…‖)

Notas do Editor
A traditional OPAC would most likelyhave missed these results.
Harmonization: to a pointRemediation:again, to a pointSOLR: the lingua francaNot really a new problem: MARC itself has changed significantly over 40+ years
A 78 with two songs, one on a side.Individual performers given in a free text note only.What if a user wanted to know more?
Page for just one “track”.Relationships to releases, cover versions (not found in traditional library metadata)User could follow any one of these links to explore further
Links could be made reciprocal.Or imagine the catalog being dynamically enhanced with these specialized facets.
And the page for the individual work.And if we follow the link to SearchWorks…
Imagine these steps in reverse: a user interested in this opera wants to find other operas premiered in the same city in the same year.
Imagine this as a dynamically-generated box within the item view page.I invite you to explore the tools further on the Linked Jazz website (e.g., a tool that allows an end user to uncover further relationships and thereby grow the network).
