Friends of Santee Library, a 501(c)(3) nonprofit organized in 1975 on Carlton Hills Boulevard, channels all-volunteer fundraising into branch programming and collection development for the adjacent county library. The organization's Friendly Used Bookstore, operating since 1993 with an inventory sourced entirely from community donations of books, DVDs, and CDs, directs every dollar of sales revenue to Santee Public Library's children's reading events, ESL materials, and the New Library Building Fund. Volunteers accept donated titles in good condition along with audio and video media, excluding encyclopedias and textbooks older than five years. Annual book-drive campaigns redistribute thousands of volumes to neighborhood classrooms along the same Carlton Hills Boulevard education corridor where Community Montessori operates its early-learning campus near Santee Lakes Recreation Preserve. The bookstore's zero-overhead structure — no paid staff, no inventory acquisition costs — converts 100 percent of gross revenue into direct library support, a model sustained under EIN 33-0197229 since the organization's 1975 incorporation.
