I stole this idea from Scott Marley, who has a section on his website for reprints of various essays posted to the usenet over the years.
At the moment there is only one item here. I have several more, but it may be a while before I track them down and post them. Most, but not all, will be about opera.
Opera librettos and translations.
Shareware sheet music.
Other web pages by Mark D Lew, on various unrelated topics.
