VuFind is a library resource portal designed and developed for libraries by libraries. The goal of VuFind is to enable your users to search and browse through all of your library's resources by replacing the traditional OPAC to include catalog records, digital library items, institutional repository, institutional bibliography, and other library collections and resources. VuFind is completely modular, so you can implement just the basic system or all of the components. Since it's open source, you can modify or add modules to best fit your needs. A wide range of configurable options allow extensive customization without changing any code.
