As mentioned in #C5U3SEW6A, MIT have opened access to all of their journal archives. People interested in computer music might particularly want to have a look at the Computer Music Journal and Leonardo Music Journal: https://www.mitpressjournals.org/loi/comj https://www.mitpressjournals.org/loi/lmj

They said they were only opening it while transitioning to a new system, but that was some weeks ago.. They are opening up all their books rom next year though.
