Ludwig is an ingame item link database and search addon that lets you quickly browse all items by name, quality, level and other properties without leaving World of Warcraft.
How to use:
Type /lw or /ludwig to open the search window, or use lw:ItemName in chat and press Tab to turn it into an item link; you can also run /lw <name> to print matches in chat or /lw q <itemID> to print a specific item link.
