User summary: Net.Trap.Book enumerates two dozen traps ranging from dangerous to lethal. Most traps are detailed only by description though a few have ASCII "art" diagrams. This very early book of traps presents materials that fairly frequently showed up in various other net book compilations over the following decade. Most of the traps are system neutral though almost all of them assume a "fantasy dungeon" type setting. A few specify spell or other effects peculiar to AD&D.
