The Chronicle of Higher Education has an post about libraries in the digital age. The post notes that digitization projects often lead to a patchwork of online materials that aren’t available within an integrated interface. This is certainly true for the time being, but steps toward integration can be seen in the WorldCat’s full catalog listings for so many different libraries and from corporations as they attempt to catalog or at least extract catalog-style metadata from information sources. For instance, Microsoft Live Labs’ pages have a note on their work on entity abstraction and the image of it is listed here. I started noticing the same sort of information in Google Search results, and here’s another sample image.
