Page Layout ⇒ Creating an index of first lines (poetry book)

[November Snow]

Hi!
In poetry books (generally on the last pages) you often find an index of first lines, a very useful feature considering that not all poems bear a title. Is there any way (I guess there is!) I could do that with LaTeX? (Actually, I use LyX, but I'm not averse to learning LaTeX commands, quite the contrary.)
Thank you.

Hello

Next time, please provide a minimal working example regarding your question.

My first guess is that you need to put every first line
into a macro that adds it to the index.
