Oregon State University releases LibraryFind® software
 
We are pleased to announce the first public release of the LibraryFind metasearch software, developed by Oregon State University Libraries. LibraryFind is free software licensed under the GNU General Public License (GPL).

In a nutshell, LibraryFind is metasearch software developed in Ruby on Rails, and released under the GNU General Public License. It does both federated and local search, provides the ability to harvest metadata collections into a local index, provides an integrated OpenURL resolver to allow for linking to full-text resources, and allows for the ability to
customize the user interface (or even to build new user interfaces!). There is a demo to a working instance of the software linked from the website (currently off of the download page).

This first public release, version 0.7,  has a number of advanced features,
such as (but not limited to):
 
* 2-click user workflow (one click to find, one click to get)
* Integrated OpenURL resolver
* 2-tiered caching system to improve search response time
* Customizable user interface
 
As this is a pre-1.0 release, there are still a number of features,
functions, and efficiencies we plan to add to the software. We encourage
involvement from others in the library community who are interested in
working on an open source metasearch product.
 
More information on LibraryFind, including information on how to download
and run the software, can be found at http://libraryfind.org.
