The Great Net Prayerbook (GNPB), like The Great Net Spellbook is a fan-made compilation and collection of cleric spells for Advanced Dungeons & Dragons (2nd Edition). The book was originally a collection of homemade clerical spells collected from the Usenet group rec.games.frp.dnd. However, as time progressed and the world-wide web became more popular, spells were submitted and collected from a wide variety of sources.
