The Shenandoah Public Library opened in 1905 with a $10,000 funding contribution from Andrew Carnegie. The library added a kitchenette, auditorium, and archives storage room in 1955. In 1988, they received a large private donation that contributed to the addition of a north wing in the library.

By 2000, the conversation to expand or add to the building began again. Suggested ideas to move the library to another location were met with strong community disapproval and by 2009, architect Pete Franks was brought on to facilitate an addition that was ADA compliant and meshed well with the original Carnegie building design. The Shenandoah Public Library now stands at 12,000 square feet and includes amenities like:

• an auditorium with a kitchenette and built-in media projector
• a meeting room space with a sound bar and wall-mounted projector 
• a seed library where patrons can "check out" fruit, vegetable, and herb seeds and contribute some of their own seeds, with materials donated by their local Extension office and horticultural clubs
• an ADA-compliant elevator that allows access to all three library levels
• low shelves for easier patron access and improved librarian sightlines
• a designated Children's space with wall-mounted interactive play sections
• desk-mounted patron tablets for in-library use
• a Hope Locker stocked with sanitary and hygienic items for people in need
• a designated Teen space area
• a MK4 Prusa 3D Printer and GlowForge
• a computer set-up with an attached baby and toddler area for working parents
• a designated staff breakroom
• a librarian-run rotating book sale
• a designated librarian workstation and a separate circulation desk
• additional library storage
• an outdoor sign that promotes upcoming library programs and events
