Chances are that many Qalamites already know of this.

Author is Lawrence K. Lo (Qalam subscriber? Sorry if I forget! Seems not,
or else, no recent posts.)

The fact that the site's author is a software engineer didn't affect my
opinion about its worth. :)
I think he's done quite a good job. WWS is in his bibliography, naturally.

His section about phonetics is just about what I have been hoping to find;
it seems worth recommending to anyone who is interested, but not prepared
to spend weeks or months of study. (Yes, there's that Post-It [tm] note on
my monitor, reminding me of Catford...)

Best regards,
