The Evergreen ILS

What is the Evergreen ILS?


The Evergreen Integrated Library System [ILS] is a complex database program in which libraries may store patron, bibliographic, and item records and transaction records. The Evergreen ILS is available as an open source product. To find out more, please visit the Evergreen Project website.
Why did you pick the Evergreen ILS to share?


The founding pilot libraries researched available open source clients and determined that the Evergreen ILS was the most compatible with the needs of participating libraries. For more information, please visit the Evergreen Indiana History page.
Do I have to join Evergreen Indiana to use the Evergreen ILS?


Anyone may use the Evergreen ILS software without joining a consortium. Evergreen Indiana offers members many other benefits in addition to sharing software and materials, including tech support, free staff trainings, access to millions of records, purchasing discounts, and much more! Check out the Member Resources page to discover all the additional perks of membership.


How much does it cost to be a member of Evergreen Indiana?


Since 2016, member libraries have been charged an annual fee based on a tiered system reflecting a percentage of their annual expenditure. Previously, fixed rates were adopted on an annual basis by the Executive Committee.  On February 14, 2023, the Executive Committee adopted a new membership fee structure proposed by a working group from among Evergreen Indiana member libraries using a tiered percentage of the evaluated annual operating expenditures of member libraries that adjusts automatically based on library expenditures.  The following table represents the tiered fee structure approved by the Council in June 2014, adapted by the working group, and adopted by the Executive Committee.  Funds are used to expand services and reduce reliance on grant funding.
