I'm not sure what you are saying here -- that there are fewer headings being assigned, or that they are not as "good" as ones assigned in the past?

Well, actually, there's nothing at all "controlled" about keyword access. It's pretty much a pot shot, or, as I've called it before, a form of dumpster diving for information. There is a huge disconnect between the results of keyword searching and the expected functionality (read: user service) of controlled left-anchored headings, and I continue to be amazed that we've been living with this disconnect for decades without ever coming to an agreement that we need a solution.[1] Instead, great effort goes into modifying the descriptive cataloging rules, while no major changes have been made in subject access. I find this to be... well, stunning, in the sense that I'm pretty much stunned that this is the case. kc [1] See Lorcan Dempsey's approach in this slide deck: http://www.slideshare.net/lisld/irish-studies-making-library-data-work-harder . It has to do with "things", which is in good part what I first found interesting about LoD. > > kyle -- Karen Coyle [log in to unmask] http://kcoyle.net m: +1-510-435-8234 skype: kcoylenet/+1-510-984-3600
