There don't seem to be a lot of decent resources on the web. Most of the articles are thinly-veiled ads for books about "How to Write Great Lyrics" or somesuch. A good portion of the rest are self-advertisements by aspiring musicians.
For those of you who are writing lyrics, I offer the following links as at least decent and informative:
Lyric or Poem?
How to write Lyrics
How to write Lyrics too

Thanks for taking the time to read...I hope it helps you improve your skills. And thanks for posting here.
