I have paper copies of the first seven issues of the Newsletter. I don't remember how I got them (maybe from Gerrie years ago), but I sent them to the Cambridge University library about ten years ago for scanning on their request, and they returned them. I would like to contribute them to some better archive than my personal bookshelf, since it seems they might be quite rare. If there is a shortage of other archival issues, I'm pretty sure I have the complete set and I would be happy to supply any missing ones to fill gaps in the archive.
One extra task in addition to producing the pdf version of each final issue used to be producing an index for the ADS and emailing it to someone in their office. I haven't done that for the last couple of issues (hoping they would have developed the capability to pick it up on their own), but if recent issues aren't showing up in ADS, that might be the reason.
