Just a note about a couple of publications which have recently appeared which highlight the use of bibliographic data to provide 'business intelligence':
Brian Lavoie, Lorcan Dempsey, Lynn Silipigni Connaway
Making data work harder. Library Journal, January 15, 2006.
This briefly reviews some recent data mining work placing it in the context of 'making data work'.
Brian Lavoie, Lynn Silipigni Connaway, Lorcan Dempsey
Anatomy of aggregate collections: the example of Google Print for Libraries. Zeitschrift fur Bibliothekswesen und Bibliographie, 52(6), 2005. pp 299-310.
This reprints the D-Lib article of the same name. I am very pleased to see it appearing here.
