The document discusses enhancements made to the OPAC (Online Public Access Catalog) at the University of Huddersfield library to make it more user-friendly and informative. Some of the new features included a spell checker, keyword search suggestions, borrowing suggestions based on circulation data mining, and connections to related works through library databases. The changes were launched gradually with a "perpetual beta" approach and required additional servers and staff support to implement and maintain the more advanced features.
