I'm embarassed to admit that I just had a look at the Amer. Mem. Collection's FAQ. Please don't tell anyone else. They have an item "14.How do I create a permanent link to a specific item in the American Memory Historical Collections? "

The full, simple and clear 75-step process is detailed at Clicky. Malcolm had the right idea that you have to find it then go back to step one, rather than link direct to what was found. They require that you search from the collection you've already discovered the piece is in, rather than an "all collections" search. Then do some stuff you never wanted to do in your life. Not at all sure it's worth it. Still...

1. Find the song in (My own page of checked collections related to song rather than their All Collections page. Much easier to go through the responses.)
2. Make sure it's the right song
3. Go back to first Resultes & note it's California Gold
4. go to that
5. search that
6. Oi!
7. Ctrl-U for page source (Netscape)
8. Find the link following "<!--" (That's "less than!--" in case the left arrow didn't come through) at bottom of this Source page & copy & paste.
9. That would be Perm link to JJ

That was easy.
Oi!
