What are the best books on anagrams?
Among the books recommended by posters to the group are Michaelsen’s Words at Play, a highly regarded work devoting several chapters to anagrams (including their history); Palindromes and Anagrams from Dover Publications, which includes many anagrams from the pre-electronic age; the anagram collection Anagram Genius, available via the Anagram Genius site; and Robert Hale’s Anagram Dictionary, most noteworthy for its section on cognate anagrams. All of these were still available for purchase as of 2007.
