No title is printed on the album, so it is usually referred to as Led Zeppelin IV, following the naming standard used by the band's first three studio albums. The album has alternatively been referred to as ZOSO, Four Symbols, The Fourth Album (those two titles each having been used in the Atlantic catalogue), Untitled, Runes, The Hermit, and ZoSo, the latter of which is derived from the symbol used by Jimmy Page for the album sleeve. Page often had the ZoSo symbol embroidered on his clothes. Upon its release, Led Zeppelin IV was a commercial and critical success. The album is one of the best-selling albums worldwide at 32 million units. It is also certified twenty-three times platinum by the RIAA, making it the third-best-selling album ever in the US. In 2003, the album was ranked 69th on Rolling Stone magazine's list of "The 500 Greatest Albums of All Time".
