The Troutdale Library is a branch of the Multnomah County Library, in Troutdale in the U.S. state of Oregon. The library, part of the Cherry Park Market Center, offers the Multnomah County Library catalog of two million books, periodicals and other materials.HistoryIn November 2009, the Multnomah County Library leased a space in a shopping center to start a branch in Troutdale. The 6000ft2 retail space was then renovated the next year by general contractor Brockamp & Jaeger. The renovations were designed by Hennebery Eddy Architects, and were completed in time for an opening in July 2010.
