Presentation Overview
Why folktales?
Who and what is being studied?
What methods are we using?
What have we learned so far?
How will we proceed?
Why Folktales?
They are complex information
resources.
Catalog records often omit
critical information.
Standard tools for access are
often complex and out of date.
No single type of user
predominates their use.
About Folklore and Folktales
Field of study is relatively
new and dynamic.
Basic requirements—
• Conveyed orally or informally
demonstrated
• Traditional in nature
• Has natural variants
No systematic definition of
folktales.
Several scholarly traditions
of engaging folktales.
Discovery and Access Tools
Tale types
• Narrative or plot structure
• Sequence of motifs
Motifs
• Actors
• Items
• Single incidents
“Some ideas have been so recurrent in tradition that we may
encounter and recognize them in a great number of ‘texts’”
(Toelken, 1996, p. 209).
Who and What is Being Studied?
Four scholars at GSLIS
• Intentional folklorists
• Teach youth-services librarianship
• Are storytellers
Folktales Collections
• ~1200 volumes included at the
Center for Children’s Books
• Primarily published for a juvenile
audience
• Publication dates range from 1880 2010
Our Research Questions
[P1] scholar [P2] practitioner [P3] lay user
RQ1) What kinds of information seeking tasks are
evident for people seeking folktales? Are tasks shared
across groups?
RQ2) What characteristics of an information
retrieval interface best support tasks?
RQ3) To what extent do current bibliographic
records support tasks? What improvements are
suggested by facet and task analysis?
What Methods Are We Using?

INFLUENCES
Kuhlthau’s (2005) call for greater connection between the
study of users' information-seeking behaviors and the
design of information retrieval systems
On the Record: Report of The Library of Congress Working
Group on the Future of Bibliographic Control (2008).
• integrating user-contributed data into library catalogs
(4.1.2),
• encouraging application of—and cross-referencing with—
other controlled subject vocabularies (4.3.3),
• supporting ongoing research about bibliographic control
(5.1.2).
STUDY OVERVIEW : TASK ANALYSIS
• Repertoire of techniques (Vakkari, 2003)
– Commonly associated with user-centered interface design
– Also used to investigate information-seeking processes
• Task is information-seeking activity necessary to
complete a goal (cf. Xie, 2008).
• Working Minds: A Practitioner's Guide to Cognitive
Task Analysis (2006). Crandall, Klein, Hoffman.

OBSTACLES
DISCIPLINARY:
Tale names vary
Tale motif / theme variants
(Cinderella)
ACCESS / DISCOVERY:
Misunderstand use of
type and motif indexes
Publication overtakes indexing
Catalogs have limited
cross-references
STUDY OVERVIEW : FACET ANALYSIS
“Sorting of terms in a given field into homogeneous mutually
exclusive facets each derived from the parent universe by
a single characteristic of division.” (Vickery, 1960).
Steps:
Define the subject field
Examine materials that reflect user interests
Develop a list of characteristics, concepts or categories
Sort these terms into facets
FACET ANALYTICAL APPROACH:
Proper and rigorous practice of facet analysis by
observing the rules of logical division.
(Broughton, 2001, p. 67; Mills, 2004, p. 268)
(1)one characteristic of division is applied at a time [conceptual
analysis]
(1) division steps should be logical and proximate
(1)division should be exhaustive (Mills, 2004, pp. 551).

FACET ANALYSIS (FA)
FACETED CLASSIFICATION (FC)
FA - (analytical technique)
• Listing of characteristics of the entities in a universe (exhaustive,
mutually exclusive)
FC - (synthetic structure)
• Division of entities in a universe (by one characteristic at a time)
FC – (structure of synthesis)
• Synthesis – combine relevant facets:
– Schedule of terms for description
– Assignment of notation
FACET ANALYSIS
Identify domain / entities
• Mapping the scope
– (Context) Examine the domain
– (Content) Survey the literature
– (Users) Who? Information needs?
• Label/ sort
– Begin analysis with a list of “standard categories” (provisional guide)
PMEST/ Who/ Where/ How/ What/ When
– Result: set of homogeneous mutually exclusive groups (facets)
– Formulate every distinctive logical category and possible relation
• Cluster /order
– In-depth analysis of categories
– Cluster terms/ objects into arrays or groups which share a common
characteristic

Facets and Folktales: Study Overview
Phase One (Supported by OCLC/ALISE and ongoing)
– Task Analyses of scholarly informants' information
seeking
– Facet analysis of the collection and common access
methods
– Importing existing records into a KOHA implementation
– Developing a prototype for enhanced records.
Phase Two (Practitioner informants)
Phase Three (Lay informants)
COLLECTED DATA
INTERVIEWS
BIBLIOGRAPHIC RECORDS (local / WorldCat / Indiana University)
BOOK CONTENT (ToC / reviews / index / introduction – notes)
LITERATURE
TYPE and MOTIF INDICES
Aarne-Thompson-Üther
tale type and motif indexes
“some ideas have been so recurrent in tradition
that we may encounter and recognize them in a
great number of ‘texts’” (p. 209).
Tale type
narrative or plot structure
specific sequence of motifs.
Motif
recurring elements from which tales are
constructed. Thompson (1946):
actors,
items,
single incidents.
FOLKLORE
Fairy tales
Folktales
Definitions of folklore are largely idiosyncratic,
Three basic requirements:
1) the object under scrutiny must be conveyed either
orally or
informally demonstrated;
2) it must be traditional in nature; and
3) the object must have natural variants as a
consequence of its
informal transmission
(Brunvand, 1996).
