The X documentation was 2 volumes: 5 inches total. If you throw in Motif, Display Postscript (which came out in early 90s on SGI) and GL, it's still under a foot. I never had NeXTSTEP manuals, but I did have the OPENSTEP box set which was about a foot thick.

I understand the point you are trying to make, but the truth is an expert would find a lot of similarity in those systems. Even today iOS development feels comfortable and similar to the work I did on SGIs in 93.

Hmm...there were a lot more than 2 volumes on that bookshelf. And again, that was just the windowing system.

Amazon [1] suggests that there were at least 8 volumes.

You are seriously trying to add up all the O'Reilly books and compare that to documentation published by NeXT?

I think I still have my books at home somewhere. They were by Digital Press if I recall.
