The Foundation is a non-profit charitable organization that encourages donations to the Tigard Public Library to support significant library enhancements and to help offset the costs of future capital improvements. Donations are tax-deductible as allowed by law.

The Foundation offers numerous opportunities to assist the Library through cash contributions; annual gifts for ongoing operations; wills and bequests; memorial gifts; insurance policies; stocks; corporate and matching gifts and more. The Foundation also provides information on how people can include the Library in their estate planning.

Founded in 2001, the Foundation ran a commemorative brick campaign in 2003-04 to raise funds for books for the new library. Supporters purchased more than 600 bricks which are located in the entryway and courtyard of the Library. Engraved bricks are no longer available for sale. The Foundation also contributed funds to commission artwork when the current Library building opened in 2004.

In order to maintain a strong relationship with both the Library Board and the Friends of the Library, representatives of both organizations have been invited to attend their meetings.
