There are many ways to find anagrams; some are more efficient than others. Some find one at a time; others find every one in the dictionary at once. Some handle single-word anagrams and some handle multi-word anagrams. We have all kinds here. We even have the particularly inefficient algorithms because it's important to learn what doesn't work as much as what does, and why the more advanced solutions need to be as complicated as they are.

• ars_magna.shar / arsmagna2 / Ars Magna II (Macintosh) / magna-gtoal (portable C)
  Ars Magna is the definitive multi-word anagram generator. Uses a real clever data structure for removing letters from a set efficiently.
• gtanag.mai
  This neat and tiny program (blush) is about as good as you can get for single-word anagrams. It finds all the anagrams within a large set of words in a single operation.
