The outwardly visible status is that just a small portion of the recordings have been made available[1]. The Archive is not commenting about this for years now.
I've donated to archival efforts before and, as many, would be happy to chip in for this one. It doesn't seem possible though and we don't know why it appears stalled.
I already do, I have donated $1750 so far. I have no way to see why this project is stalled or to specify where my donations go to (which makes sense, having donators specifying which subproject is likely to be a nightmare to manage)
