I packaged the 2016-01 parts library for Fedora 25 to install to /usr/share/ldraw; it should be straight-forward to adapt to other distributions.
The *.noarch.rpm files are the ones to install, and the .src.rpm contains everything so it can be rebuilt for another rpm-based distribution.
When they reached out to me, I was happy to have my Lego Rubik's cube included in their book, though a bit surprised given the relative simplicity of the creation. When my copy arrived, I was pleasantly surprised to have gotten four pages in the book.
They have included a wide variety of projects which incorporated Lego parts as a material; from clothing accessories to furniture to home remodeling. People really do a lot of weird things with Lego.
