Princeton Public Library

What Princeton Public Library does

Princeton Public Library is a municipal public library serving the Municipality of Princeton, New Jersey, in continuous operation since December 30, 1909. It is funded primarily through municipal tax appropriations, supplemented by tax-deductible donations through its Friends and Foundation organization, proceeds from a gently-used bookstore, and fee-based library cards for non-residents ($35/month or $250/year; $150/year for seniors). The library operates from a single location at 65 Witherspoon St. (the Sands Library Building), employing 51-100 staff, and serves a community of Princeton residents and property owners with free library cards, while also extending access to Princeton University and Princeton Theological Seminary students.

The library's core product portfolio combines traditional collections with non-traditional services. The eLibrary platform aggregates ebooks, audiobooks, magazines, newspapers, comics, streaming video, and music through third-party apps (Libby, Hoopla, Palace Project). The Library of Things circulates non-traditional items including Chromebooks, mobile hotspots, projectors, cameras, and nature exploration kits. Research databases span Ancestry Library Edition, HeritageQuest, FamilySearch, Fold3, LinkedIn Learning, Tutor.com, Mango Languages, PressReader, and ProQuest. Technology services include public computers, MacBook lending, 250 Mbps Wi-Fi, printing/scanning/faxing, VHS digitization, and access to Adobe Creative Cloud and Apple Pro Software. Specialized spaces include the Myra and Van Williams Spark Lab (STEAM education) and study rooms with Solstice wireless screen sharing. Adjacent services include museum passes, PPL BookMatch personalized recommendations, and the Voices of Princeton oral history initiative.

The library's go-to-market is community-led and event-driven, with no commercial sales motion. Patron acquisition runs through social media (Facebook, Twitter, Instagram, TikTok, LinkedIn, YouTube, WhatsApp in Spanish), email newsletters segmented by audience (Kids, Teens, Films, Lectures, Performances, Technology), a content blog, and a dense partnership network that includes Princeton University, Historical Society of Princeton, Morven Museum & Garden, RevolutionNJ, Gilder Lehrman Institute, NEH, and the NJ State Library. The library's customer base is segmented horizontally across general residents, children and teens, educators, business professionals and job seekers, genealogists, and humanities scholars — with no enterprise or commercial anchor accounts.
