Welcome to the Evergreen project site, a powerful and scalable software solution designed for libraries that assists patrons in locating library resources while enabling libraries to effectively manage, catalog, and circulate materials, regardless of their size or complexity. The Evergreen Project is dedicated to creating an open-source integrated library system (ILS) that is currently utilized by over 2,000 libraries worldwide. Known as Evergreen, this software provides a public catalog interface for libraries while also streamlining essential back-end functions such as circulation, which includes checkouts and returns, acquiring new materials, and facilitating resource sharing among different library networks. The functionality of Evergreen is built upon a diverse array of technologies, including Perl, C, JavaScript, XML, XPath, XSLT, XMPP, OpenSRF, Apache, mod_perl, and PostgreSQL. For those looking to implement Evergreen, it is advisable to use the latest stable release of a compatible Linux distribution to ensure optimal performance and support. This robust platform not only enhances the user experience for patrons but also significantly improves operational efficiencies for libraries.
