Greetings to all!
I wonder where I can find digitised versions of old talking books recorded for the blind, on gramophone discs (most often at the speed of 16 RPM), or reel-to-reel tapes.
I have a collection of such books in Serbian, as they are available in our libraries, and freely circulate among the blind, but I am curious whether a collection of such material is available in English, either British or American.
I would be grateful for any answer.

Well I know sometimes the National Library Service here in the United States might digitize older recordings from cassette, I distinctly remember a version of Charlotte's Web being digitized from record when I was a little kid. I'm not sure, but I don't think we here in the U.S would have used reel to reel tape, but I don't know, I wasn't alive at that point. I know we did use records and cassette tapes though.

I remember my older brother getting Galaxy magazine in reel-to-reel format. I don't remember any talking books in that format. Galaxy may not have come from NLS, but I'm very vague on such details. I was so young then.

To be honest I don't know what reel-to-real tape means. When I was younger for a long time I used to get these tapes that played on a lower speed, and on a pate recorder that played on a selecter switch. So you could change it from side1 to side 3 for example. Then later it was the daisy player. Now I've lost track, I haven't received any audio books in years. I guess they are all available online. I realise this doesn't quite answer your question. But I hope you find this information interesting.
