# Skyscape > Licensed clinical reference for practising clinicians, on the device they > already carry. 377 titles from 32 publishers across 33 specialties, > available offline. Skyscape has published clinical reference since 1993. Skyscape licenses the reference works clinicians already trust — Harriet Lane, Ferri's Clinical Advisor, the Washington Manual, Harrison's, Tintinalli's, Netter's, Davis's Drug Guide, Taber's — and delivers them on iOS, Android and web. Content is downloaded to the device, so it works without a signal. Most clinicians do not buy one title. They buy a **Constellation**: a bundled set covering a specialty, priced well below the sum of its parts. ## What Skyscape is not Skyscape is not a general medical search engine and does not publish its own clinical content. Every answer comes from a licensed third-party reference work and names its source. Skyscape does not sell advertising and does not accept sponsored placement in clinical content. ## Reference titles A selection of what is licensed.
