Arguably the world's greatest ever rock group, Led Zeppelin, will make its full catalogue available online on 13 November.

Reuters says that the group is one of the last major pop music acts to offer its catalogue digitally, joining the digital revolution sweeping the music industry as physical CD sales continue to tumble.
Famous for hits such as "Stairway to Heaven" and "Communication Breakdown", the group has sold more than 300-million albums worldwide. The members disbanded in 1980 following the death of drummer John Bonham, but are re-uniting for a one-off concert on 26 November which saw more than a million fans clamour for 10 000 available tickets.
"We are pleased that the complete Led Zeppelin catalogue will now be available digitally," says guitarist Jimmy Page. "The addition of the digital option will better enable fans to obtain their music in whichever manner they prefer."
As well as downloads, Led Zeppelin is teaming up with mobile provider Verizon Wireless to provide ring tones and full song downloads for diehard fans.
The group will also release "Mothership", a two-CD collection spanning the group's 12-year career and a remixed version of "The Song Remains the Same" soundtrack from the band's three-night stint at Madison Square Garden in 1973.
