Pretty much every 3rd party LEGO book that has instructions in it uses some form of the LDraw library. LPub was developed by Kevin Clague because he was writing a book and wanted an easier way to make instructions. Also, there's at least 3 books out there (that I know about) that are devoted to LDraw itself (and many more with a chapter discussing LDraw)
