I'll have some detailed feedback ready for you once I'm in a place where I can listen to it (I've misplaced my ear buds, alas), but I wanted to leave a quick comment to let you know how much I enjoyed this post.

Re: LibriVox, have you listened to any of the recordings for Jazz Fantasia? I stumbled across a set of them some years ago, and especially enjoyed the first and seventh readings (the readers were Alan Davis-Drake and Ianna Drake respectively).

Re: taking notes on poetry and practicing them prior to recording, I'll definitely keep that in mind as I start recording pieces that I don't already know by heart. (Yesterday's recording of 'Books' by Billy Collins is one I've declaimed live to an audience.) I'm curious: how many takes you usually do before you have a recording you feel satisfied with? Right now I'm averaging about forty-five minutes from opening Garageband to record to exporting the mp3 to iTunes, and about four to six takes.

Re: saying poetry aloud, it reminds me of a conversation I had with smw a while back re: writing poetry: I depend a great deal on internally 'hearing' the words and comparing the sound-feel-resonance of the various ways they might combine into phrases.
