The band are also releasing new versions of the first album and its two successors (What's The Story) Morning Glory? and Be Here Now, which will feature unreleased and rare recordings.
The original demo tape, which the band created to drum up interest in the group in the early 90s, included early versions of tracks such as Columbia, Rock 'n' Roll Star and Married With Children.
Only eight copies were ever created.
On Wednesday many fans were left disappointed as news of a special announcement regarding Oasis led to speculation that the group may reform for the anniversary.
Oasis came to an end in 2009 after guitarist and main songwriter Noel Gallagher quit the line-up, after years of friction with his brother Liam, the group's singer.
The Gallagher brothers - who are still not on speaking terms - have consistently said there were no plans to get back together.
Liam said recently: "There is no band. So, no, I won't be getting involved, anyway. If there is a reunion, I won't be in it."
