You can probably find books of word-lists in your nearest bookshop.
These are generally of two types: they may be a simple list of words
or they may arrange their words by subject (birds, bees, etc). Of
the latter type, the classic American publication is Baus's "The
Master Crossword Puzzle Dictionary". Of the former, the classic
British one is "Chambers Words", which contains, or purports to
contain, all the words in Chambers English Dictionary, listed by word
length and then alphabetically. It has numerous errors, which are
not corrected in subsequent additions. See "What errors are known in
Chambers Words?". On the other hand, the errors still represent a
tiny percentage of the whole, and Chambers also publishes "Back
Words" (words listed in reverse alphabetical order) and "Anagrams"
(words indexed by their letters collected into alphabetical order, so
"anagram" is under "aaagmnr"). The New York Times also publish an
adequate word-lists book. See question 6.
