Evergreen is an enterprise-class library automation system that helps library patrons find library materials, and helps libraries manage, catalog, and circulate those materials, no matter how large or complex the libraries.
Development priorities for Evergreen are that it be stable, robust, flexible, secure, and user-friendly. Evergreen’s features include:
* Circulation: for staff to check items in and out to patrons
* Cataloging: to add items to the library’s collection and input information, classifying and indexing those items.
* Online Public Access Catalog (OPAC): a public catalog, or discovery interface, for patrons to find and request books, view their account information, and save book information in Evergreen “bookbags.” The OPAC received a makeover in early 2009 with the new, optional skin, Craftsman.
* Statistical Reporting: flexible, powerful reporting for retrieval of any statistical information stored in the database.
* SIP2 support: for interaction with computer management software, self-check machines, and other applications.
* Acquisitions, Reserves, and Serials Modules are under development and the first versions of these will be launched with Evergreen 2.0, due out in 2009.
As much as possible, Evergreen shuns workarounds and kludges often ingrained in library workflows and legacy software, such as the use of fake records and overloaded fields. The software is designed to scale up with organizational complexity as well as transaction and indexing loads. Evergreen’s library policy uses an inheritance model which allows for rich, flexible, easily-tuned local control as well as high-level abstractions.
Evergreen also features the Open Scalable Request Framework (OpenSRF, pronounced “open surf’), a stateful, decentralized service architecture that allows developers to create applications for Evergreen with a minimum of knowledge of its structure.
