[2] Beyond PINES, the Evergreen ILS is deployed worldwide in approximately 1,800 libraries, and is used to power a number of statewide consortial catalogs.

GPLS believed it could develop a system customized to fit its needs better at a lower cost than the fees currently being paid.

[11] Programmers in the GPLS developed the project for two years, and PINES successfully completed the transition to Evergreen on September 5, 2006.

In the next two years, the PINES consortium increased to over 270 libraries and five other systems in the United States and Canada implemented Evergreen.

The staff client used in day-to-day operations by library staff runs on Microsoft Windows, Macintosh, or Linux computers and is built on XULRunner, a Mozilla-based runtime that uses the same technology stack as Firefox and allows for a browser-independent offline mode.
