The document discusses opportunities to improve online public access catalogs (OPACs) and move them towards an "OPAC 2.0" model. It summarizes surveys that found users give low ratings to existing OPACs and describes efforts at the University of Huddersfield to enhance their system with features like spell checking, keyword suggestions, and integration of library resources. The presentation advocates for an experimental and user-centered approach to OPAC development, and highlights open-source systems and web services that can power new features to create a more modern online experience for library users.
