The document discusses the future of online public access catalogs (OPACs) in libraries. It begins by describing common complaints about current OPACs and proposes features for OPAC 2.0, including spell checking, search suggestions, user reviews and ratings, personalized recommendations, and integrating the OPAC into other sites. It then summarizes the results of a survey of librarians which found strong support for improved features like embedding the OPAC elsewhere and adding enriched content. The document concludes by discussing technology adoption trends and the need for libraries to implement new OPAC features to better meet user expectations.
