In the main type of anagram ictionary, the letters in words or phrases are rearranged in alphabetical order, and these transpositions are themselves then ordered alphabetically within word-length groups, so that any words consisting of this group of letters can be found. This arrangement is designed for use in solving word puzzles such as crosswords, or for playing games such as Scrabble. The first such anagram dictionary was the "Crossword Anagram Dictionary" by R.J. Edwards, published in 1978 by Barrie & Jenkins in the UK and Mayflower Books in the US.
