Product Introduction Overview:
"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, Locally Cached Journals,
Digital Library Items, Institutional Repository, Institutional
Bibliography, Other Library Collections and Resources. VuFind is
completely modular so you can implement just the basic system, or all of
the components. And since it's open source, you can modify the modules
to best fit your need or you can add new modules to extend your resource
offerings. VuFind runs on Solr Energy. Apache Solr, an open source
search engine, offers amazing performance and scalability to allow for
VuFind to respond to search queries in milliseconds time. It has the
ability to be distributed if you need to spread the load of the catalog
over many servers or in a server farm environment. VuFind is offered for
free through the GPL open source license. This means that you can use
the software for free. You can modify the software and share your
successes with the community! Take a look at our VuFind Installations
Wiki page to see how a variety of organizations have taken advantage of
VuFind's flexibility. If you are already using VuFind, feel free to edit
the page and share your accomplishments. "
