I've been looking for On the Loose for years too, though sporadically. It's good to know that the Girl Scouts can be a good source. Do you have a particular contact or department you'd recommend? (Pm me if you don't want to post it for posterity). While I don't know what different resources I have available, I'd be happy to pitch in for Barges and Spider's Web.

And what a coincidence, I found that copyright list last night too! An invaluable resource (and I've already messaged the site master since "On the Loose"'s entry indicates that she got permission.)
