Many libraries are implementing or developing web-scale discovery interfaces or other faceted browsing interfaces. There is exciting potential for new discovery interfaces to ease the difficulties users face when searching for music materials. However, the specialized discovery needs arising from unique characteristics of music materials are often overlooked. This session will examine how to meet the special demands for music discovery while improving access to materials that pose similar challenges, such as law, literature and religious studies, and video collections. The session will provide an overview of the topic, based on the Music Library Association’s Music Discovery Requirements document, and explore aspects of music discovery as realized through specific interfaces.

Discovering Music: Small-Scale, Web-Scale, Facets, and Beyond
- 1. Discovering Music at Cornell Tracey Snyder, Assistant Music Librarian NASIG June 8, 2013
- 2. The story of us Our current situation Our Blacklight implementation Our bento box aspiration
- 3. Current situation WorldCat Local for local and global holdings (useful for ILL and Borrow Direct) Classic Catalog (Voyager OPAC) for local holdings (recommended for music) Summon (articles, ebooks, streaming A/V) Music library homepage also provides direct links to heavily used resources (Naxos, Music Online, RILM, Oxford, etc.)
- 4. Easter egg
- 5. Blacklight implementation Discovery & Access Implementation Team in place since summer 2012 Groups: User representatives, User experience, Developers Beta release for library staff spring 2013: http://search.library.cornell.edu/ Useful feedback from library staff Public beta release next academic year
- 7. Bento box aspiration Single search box that searches across catalog, articles, library websites, etc. Sampling of results from each silo presented in panes (like a bento box) NCSU is a model Aiming for spring 2014 release
- 9. My story for you Our current situation Our Blacklight implementation Our bento box aspiration
- 10. Blacklight—my role User representative Coordinator of usability testing for music Champion of the Music Discovery Requirements, created by members of the Music Library Association’s Emerging Technologies and Services Committee If you can get your system to work well for music, it will work well for anything.
- 11. Blacklight—my pet issues Publisher number—index and display Sound recordings in the format facet CDs vs. LPs, etc.? Streaming audio? Subject/genre facet(s) Uniform title click-to-search functionality Assorted others not exclusive to music
- 12. Usability testing for music Cognitive walkthrough (task-based) Session with music library staff (6) Session with a real live music student 7 music-specific tasks, designed by me and vetted by other members of both the Discovery & Access Implementation Team and the Usability Group
- 13. The tasks I asked Find a score for Arches by Fred Lerdahl. Finds streaming audio for Mozart’s clarinet concerto. Find documentaries about punk music available at the music library. Find books about the 19th century German symphony. Find books in English about wayang at the music library. Email some to yourself.
- 14. The tasks I asked (cont’d.) Find Grove Music Online. Find all sound recordings at the music library that contain all of Beethoven’s piano sonatas.
- 15. What they liked Design Facets Format icons Relevance of results, location facet, search history, export, cite, email, text Publisher number search (although not yet enabled at the time of testing) Combined subject/genre facet Subject heading click-to-search (but…)
- 26. What they didn’t like Can’t select multiple options in a facet… Weird “did you mean” suggestions—fixed! Streaming audio files not showing up as sound recordings in format facet—fixed! “Documentary films” (from MARC 655) not displaying in the record—fixed! Uniform title click-to-search not retrieving expected results—will be fixed.
- 30. ?
- 31. !
- 36. The impossible question How are we going to simulate Voyager’s “Author--Sorted by Title” search mode when the Classic Catalog interface is no longer available to users?
- 37. “Author—Sorted by Title” How it is used Why it is so important for music Coming up with use cases Conveying the nature and importance of this esoteric search function to other members of the Discovery & Access Implementation Team
- 46. What the future holds RDA elements—a new granularity Genre/form thesaurus Medium of performance thesaurus What about legacy data? Question of music-specific skin— drawbacks/limitations
Hinweis der Redaktion
- WCL, Summon, Classic Catalog (Voyager)
- What is Blacklight? In a few words. Open source, faceted discovery interface, Solr index, UVa. Relevancy ranking, stemming, cover art. Other features. Looking at other implementations of Blacklight, esp. Stanford. Caveats about our beta. Slow. Incomplete. More fixes coming soon, so wait a week or two before looking at it.
- NCSU is our model. Several other places are going in this direction, too.
- I’ll mostly be talking about my role in bringing the music perspective to the development of our Blacklightimplementation.
- Other stuff: Indexes, display labels, results list, advanced search… Also displaying subfields in correct order in 6XX and UTs.
- Generally positive feedback, but still some nagging issues at the time of testing. Some new issues exposed.Brought out problems and perspectives that I had not even considered. Confirmed my assertions about my pet issues.
- The first four—pretty standard features for a discovery tool. The final three—local decisions/configurations.
- How/why a music researcher would use this, for scores and recordings. Score example using an old plate number. Looking for a specific edition, or a reprint of it.
- Found a 2011 reprint using the plates from an 1865 edition.
- Sound recording example using record label catalog number. Discography on Blue Note label. Looking for this Blue Note catalog number (an album from 1964).
- Found a CD reissue of the 1964 album.
- Decision to make a combined subject/genre facet (but still separate region and era facets). Musical genres/forms (as well as medium of performance) are all coded in 650, along with topical subject terms. “Ballets” for scores and recordings of ballets, “ballet” for books about ballet. (Results of a Stravinsky search).
- A score of a ballet (Rite of spring) by Stravinsky.
- A book about ballet and Stravinsky.
- Click-to-search subject strings—can click on the “19th century” segment of the subject string and get other resources that also have this same exact string (as opposed to all resources that simply contain “19th century”). However, no visual indication of this functionality—something to think more about.
- Bonus feature: TOC display. For comparison, here is what the contents note looks like in Voyager. In the 505, works in a compilation are separated by a double dash. Can get very lengthy and hard to read.
- Much prettier in Blacklight!I didn’t even ask for this! A clever programmer thought of it (converting the double dash to a line break). Easier to scan works listed in contents note and see how they correspond with the controlled version (the added entries).
- Should we provide check boxes to enable multiple selections within a facet, like WCL does? This issue tabled for now.May come back to the question of hierarchy within the format facet (distinguishing among CDs, LPs, etc. in the sound recordings category).I hadn’t even noticed the streaming audio categorization problem until someone pointed it out in the group test. Fixes visible soon—later this month.
- BEFORE. Naxos Music Library results showing up as computer files (via facet and icon), not musical recordings.
- AFTER. An intrepid programmer mapped the values from local MARC subfield 948 $f (eaudio, evideo, escore, etc.) to the appropriate formats.
- Looking for punk rock documentaries. Taqwacore is first result after selecting “documentary films” in the subject/genre facet.
- BEFORE. “Documentary films” selected in the subject/genre facet, but not displaying in the bib. Mixed data: film genres like this are coded in 650 in older records, and 655 in newer records. Must include both 650 and 655 (in fact, all 6XX) in facet and in bib display.
- AFTER. There it is! Now displaying all 6XX in bibs.
- I don’t have BEFORE and AFTER shots for this issue since it is not fixed yet, so here is what we are aiming for, using Stanford as a model (with their permission).If you click a uniform title for the complete set of Beethoven piano sonatas,…
- …you get other resources that contain the complete set of Beethoven piano sonatas.
- If you click on a uniform title for a specific sonata,…
- …you get other resources that contain that specific sonata.
- This search retrieves 2948 resulting titles entered under Beethoven. He was very prolific. But it is a finite, comprehensive, browsable, alphabetical list. These are not titles of library resources, but rather they are uniform titles and cross-references, all coming from name-title authority records.
- Leverages cross-references from name-title authority records. “More info” next to a cross-reference tells you to instead search by the uniform title. Waldstein sonata (as it is commonly referred to) is not actually the uniform title. Very useful for prolific authors or composers, especially with works with generic titles, like Sonatas.
- Search under this uniform title instead (for Waldstein sonata).
- Pulls together all 36 library resources that contain this sonata, even if the resource presents the title as the more familiar Waldstein sonata. Also allows you to browse the possibilities. A result for just the Allegro con brio from this sonata.
- This search retrieves 7643 resulting titles entered under JS Bach. He was very prolific. But it is a finite, comprehensive, browsable, alphabetical list. These are not titles of library resources, but rather they are uniform titles and cross-references, all coming from name-title authority records.
- Leverages cross-references from name-title authority records. “More info” next to a cross-reference tells you to instead search by the uniform title. BWV 971=ItalienischesKonzert. Very useful for prolific authors or composers, especially with works with generic titles, like Concertos. Also allows you to browse the possibilities. A result for just the Adagio from 974. An arrangement of 974. Very useful if you are not sure which BWV you are looking for. This list jogs the memory. (“I’m looking for a harpsichord concerto in D major [a very popular key signature!] in the 970s.”)
- If you are looking for the one in F major, search under ItalienischesKonzert instead.
- We also have 3 resources that contain arrangements of the ItalienischesKonzert. Serendipity.
- Genre, form, medium of performance—tied up in subject headings, with topical terms. Two projects in development to separate them out (Library of Congress and Music Library Association).But even after these are completed, a huge body of legacy data will remain. How to deal with that in facets, etc.? A music librarian from UVa mentioned ongoing usability concern with their music skin—people don’t realize that it’s still searching the same pool of library resources, just with different facets.Also, hard to populate an instrumentation facet given the realities of legacy data and copy cataloging.
