I linked to the draft version before, but now the final version is out: The Changing Nature of the Catalog and Its Integration with Other Discovery Tools (175 KB PDF) by Karen Calhoun of Cornell University Library, prepared for the Library of Congress.
As noted earlier, applying FRBR concepts to improve the user’s experience with catalogs was often mentioned by interviewees. Much is appearing in the library literature about deploying FRBR concepts [71, 72, 73, 74, 75]. There is excitement around the Research Library Group’s RedLightGreen  and OCLC’s work-based catalog investigations such as Curioser .
Feel the excitement!
