User summary:
The LaTeX Net Spellbook has been credited as the first-ever true "netbook", being distributed in LaTeX format on rec.games.frp on August 11, 1990. The netbook was compiled and formatted by Matthew Presley. It was distributed as thirteen separate files, one for each spell level and several front-matter materials. While distributed and referred to as The LaTeX Net Spellbook, the cover curiously bore the title "Frost".
The LaTeX Net Spellbook was recycled frequently, in various formats - for example, some of the contents appeared later in The Great Net Spellbook.
