Ahhh Howard I was going to suggest county record offices. I started a thread a few months back on a subject approaching just this. Unfortunately some reocord offices don't want to know, because they just don't have the space and/or the staff to deal with them. Luckily Essex Record Office is fairly accommodating. Yeah I work there.

I would suggest to Deckman if you are recording for posterity make your first copy on high quality archive CDs. They last longer and if you find an outfit to house the collection they will likely require this.

Now I need to take some of my lunch time to have a listen to those tapes from the Chelmsford Folk Club.
