All of the shows on this list are available as archived shns. For the majority of the Grateful Dead shows, the md5 files match those in the etree db. However, I do occasionally trade audio discs with others who are not yet enlightened as to the advantages of the shn format. When I receive such an audio trade, I generally do a careful EAC extraction, and shn up the result, just for my own archives. I then toss the audio discs on the floor of my car, with the rest of them. The shns generated in this manner will generally not match those in the etree db. How to tell: if the "shn link" field is populated on the list entry, then my shns match the md5s available at the linked version of the show. If the "shn link" field is not populated, the notes generally offer some guidance as to the source of the shns. I can do FTP trades, but do not run a server. I also do snail mail trades. I am generally willing to do B&P's. Finally, pay no attention to the "Locator index" field on the list. It's an index into the shn collection.
