Didn't they just re-issue a few of their albums as well? A friend of mine happened to mention it.
Yes, on multiple occasions. They're an older band, so naturally things are occasionally remastered and reissued. My information could be inaccurate, but Jimmy Page spent some time in 2014 remastering their discography. Most recently, their compilation album BBC Sessions was subject to the same treatment.
It was originally a compilation album featuring nine studio sessions and a live concert recorded for the BBC, released on November 11, 1997 by Atlantic Records. The first new release in seven years, I believe. The first disc contains material from four different 1969 BBC sessions, while the second contains a concert recorded in April 1971 at the Paris Theater in London.
The album was re-released in September 2016 with further BBC recordings, including the "Sunshine Woman" session.
