I used to post at the Steve Hoffman forums. I wouldn’t think the Music Corner was the place for a wants list. I agree that a Memory Lane advert would be a good idea. I have had some responses to my Mini Display adverts in the past. Although one reader had some records I was after and hadn’t bothered to get in touch! I bought them off him. I’ve also advertised in For the Record, the magazine for members of the City of London Phonograph and Gramophone Society. Members get a free display advert. There are some adverts on the website (see Adverts section), but they don’t seem to be updated very often, and it would only attract people who actually make the effort to look, unlike in a magazine. You could try contacting dealer Mike Comber, see [url] https://www.clpgs.org.uk/trade.html[/url]. He mentions wants lists.

Philip Hutchinson, who runs Philip’s 78s Graveyard on eBay, may also be worth contacting with your list.

There is also the King’s College Sound Archive, though I think they charge similar rates to the British Library.

I wonder if I should try the Talking Machine forum for my wants list!
