Is there a Sword Art Online manga?


So I was wondering if there is a Sword Art Online manga, and if so which is
the original, the manga or the anime?




_Sword Art Online_ started as a [light novel
series](http://en.wikipedia.org/wiki/Sword_Art_Online#Light_novels) (in 2009),
and spawned [five manga
adaptations](http://en.wikipedia.org/wiki/Sword_Art_Online#Manga) (starting in
2010) and [an anime](http://en.wikipedia.org/wiki/Sword_Art_Online#Anime) (in
2012). However, to my knowledge, the anime is based entirely on the first four
volumes of the light novels and does not borrow from the manga material at
all.
