There was also SVR3 (which I believe was the basis for the referenced AIX 3 shared
library work). SVR3 shipped in 1987, SunOS 4 in May 1988.
There was a swarm of UNIX shared library projects during the 1980s. Some of those
preceded or were occurring contemporaneously with SunOS 4. Many reached at least a running
prototype stage, perhaps deployed as specials for customers, and some reached product
status.
I believe NEXTSTEP 1.0 supported shared libraries out of the box too, probably from work
on Mach or the Andrew system at CMU.
