Nate Hill’s post about library cards as service avatars, and the Playful Librarian’s about desire lines across (information) architecture tie in to the same thing, and, not to come over all Annoyed Librarian, but it’s not David Lee King’s engines-not-OPACs thing…
Libraries are a very odd sort of space, and bound by the kinds of space-y things people run up against all the time, like sequential time and scarcity of resources. None of these really have anything to do with human thought, which is a transitional thing moving from one point to another (accurately, if poorly, rendered in the essay, and it’s emphasis on structure and argument), which libraries attempt to render via classification schemes that create (metaphorical) shelves of related items, and put these on (physical) shelves of metal. These metaphorical shelves are not fixed, and slide across the physical shelves depending on the demands of the (entirely arbitrary) physical dimensions of the resources they consist of.
Everyone already knows that this compromise isn’t ideal. Resources have multiple possible shelf-marks listed on the catalogues themselves, while the indexes of classification systems have multiple routes to the same numbers (this means you, Israel/Palestine/DDC 956). More to the point, books themselves (it’s probably clear I’m talking in the academic context by now) are often collections of threaded essays, rather then a single lengthy one. Even Ranganathan was wrong: the real point is each chapter, each paragraph, each line has it’s reader, each reader her… etc.
The library doesn’t have to simply funnel free resources into advertising-subsidised social networks, as King valorises (although free things and people doing with free things what they will are both important); it — and its related discipline of scholarly communication — already is Hill’s service avatar, but needs to build on the behaviours it already supports and extend these outwards, showing the worn patches of ground between data, across the walled gardens of documents.
