Good point.    I've forgotten as to where and when did ranlib appear in the dev stream?   Was it research, UCB or somewhere else like on the Harvard Tape?

Just now, I took a quick peak at the 1BSD archive on TUHS.org but the subdirtectories are all packed up as v6 ar archives (cont.a files) - i.e. when somebody converted the BSD stp tape to a tar image they just wrote the archive and then rewrote it as a compressed tar ball.  So I will take a little more work to unpack them, ensure the dates are 1978 based. (which I'll do at some point and offer them back to Warren).

But I do remember when ranlib showing up it was such a win for fixing C compiler (well linkage) errors.  I could have sworn, we had it was before V7, so maybe it came with the Typesetter C or UNIX/TS stuff.
