british vs. north american englishes

[Arnold M. Zwicky]

a colleague asks if there is "a good overview work comparing British
and North American Englishes".  assuming that this colleague is
interested in the standard varieties, and in all aspects
(pronunciation, grammar, orthography, lexicon), and wants something
short, i've recommended chs. 2-4 of trudgill & hannah (2002), the 4th
ed. of International English.

any other suggestions?
