  • Social Cataloging in the Libraries
    Charlie Terng

    December 03, 2009
  • Main Issue:
    Traditional classification system
    (controlled vocabulary)

    - vs -
    Social tagging
  • Terminology
    Controlled vocabulary
    An organized collection of words/phrases/names, structured to show the relationships between terms and concepts.
    Examples: LCSH, MeSH.
    Tags
    User-generated metadata used to describe the “aboutness” of an object.
  • Main differences
    Controlled vocab:
    Authoritative.
    Structured as a hierarchy.
    Ordered, systematic way to search for information.
    Tagging:
    Derived by the general public.
    Unstructured.
    More approachable, user-friendly way to search.
  • Issues with controlled vocabulary
    Hierarchy structure and specific terminology requires users to be knowledgeable or familiar in the subject area.
    Pre-determined listing takes user element out of it.
    “Look, but don't touch”. Non-interactive.
  • What tags can offer
    Cataloging system based on terms used by “regular people”.
    More intuitive way of searching.
    Free-flow path, no hierarchical structure.
    Current, up-to-date terms.
    Most importantly, more access points.
  • Example
  • Example
    Library of Congress Subject Headings
  • Example
    LibraryThing tags
  • So why not just use tags?
    Quality/relevance of tags may vary (i.e., “spagging”).
    Tag clouds, evaluation by librarians are possible solution.
    Issues with specificity (i.e., squirrel topics).
    Although, LT's new “Tagmash” seems to fix this.
    Controlled vocabulary better for total recall.
  • Which should OPACs use?
    Not “either or”, but an integration of both.
    Their strengths cover each other's weaknesses.
    Different situations call for different methods.
    They also work well together.
    It's all about increasing access points.
  • LTFL is on the job
    1,512 libraries served.
    37 in NJ:
    LOGIN (20 libraries)‏
    Atlantic County System (10 libraries)‏
    Mount Laurel
    East Brunswick Public
    Camden County College
    Highland Park Public
    Cranbury Public
  • LibraryThing perks
    I see dead people's books.
    Tagmash
    Reviews, recommendations, booklists, etc.
    Will I like this?
  • Questions, comments, etc.
