I was wondering is there any way to get old TV guides, like from the 80s or something? Just to see what was broadcast and when. I imagine there would be some kind of database although it would probably be immense.
There's a wonderful shop in Newport Pagnell which is full of all sorts of 'printed ephemera', including old TV guides. If your travels take you along the M1, it's well worth a browse.
Alternatively, you can buy by post.
Great shop, pity about the website (but at least it's got the contact details): http://www.kens.co.uk/
