A much better than average report on the relationships between librarianship and the values of libraries and the values held by the media savvy, technology-centered students of today. Describes the two sets of values, and describes how libraries can adabt to the new expectation in meaningful ways.
 

pg 99 "It is clear that Millennials and others comfortable with a wide range of media and technologies will redefine the traditional manifestations of research and creative activity with these new mashed, cut and pasted creations. For them, the line between consumer and creator is blurred in a way that previously was not possible."

pg 100 "Clear rifts have emerged in the virtual terrain that is occupied by library policies, services and collections and is explored by online users. These rifts or disconnects can be grouped into three classifications for redress. These include technology (infrastructure and integration), policy (copyright, IT policy, liability), and unexploited opportunities."

Looks at the development of various classification systems leading up to tagging, or user created metadata. Argues that tagging more closely mirrors the nature of web information.

Argues that ontologies are a bad ideal for organizing the world online. Points out that library classification systems are designed to optimize space on the shelves, not to describe the essences of identities. Also, that library classification systems are fundamentally about organizing books, not about organizing the enormity of human knowledge. The same flaws exists in a hierarchical file system. That it is designed with the assumption that a thing can only be in one place at one time -- it makes some attempt to have the organizional structure of ideas match the physical world, where in fact a pointer, or an idea, or a metaphorical path can be in countless places at the same time, and can have many equally important and useful relationships which describe it.

That ontologies are useful where there are expert users, clear categories and a limited domain. But, much less useful for non-expert users or large domains, and fuzzy categories. Links are the universal pointers on the web, and the addition of tags is simple, and provides a much more useful finding system than an ontology. With a system like delicious, you get to know who's doing the tagging, not just what the tags are, so you get to limit searches by people and time, limiting the size of your group [penntags tie-in].

Very clear pros and cons of folksonomies versus more traditional classification systems. Looks at when and for what each kind of classification is most useful.

A Columbia Librarian posted a long article about tagging systems and their use in libraries. Interesting reading.

A beautiful brief essay about tags.

This paper analyzes the tagging patterns exhibited by users of del.icio.us, to assess how collaborative tagging supports and enhances traditional ways of classifying and indexing documents. Using frequency data and co-word analysis matrices analyzed by multi-dimensional scaling, the authors discovered that tagging practices to some extent work in ways that are continuous with conventional indexing. Small numbers of tags tend to emerge by unspoken consensus, and inconsistencies follow several predictable patterns that can easily be anticipated. However, the tags also indicated intriguing practices relating to time and task which suggest the presence of an extra dimension in classification and organization, a dimension which conventional systems are unable to facilitate.
